Who is Ron Spomer
For 44 years I’ve had the good fortune to photograph and write about my passion - the outdoor life. Wild creatures and wild places have always stirred me - from the first flushing pheasant that frightened me out of my socks in grandpa’s cornfield to the last whitetail that dismissed me with a wag of its tail. In my attempts to connect with this natural wonder, to become an integral part of our ecosystem and capture a bit of its mystery, I’ve photographed, hiked, hunted, birded, and fished across much of this planet. I've seen the beauty that everyone should see, survived adventures that everyone should experience. I may not have climbed the highest mountains, canoed the wildest rivers, caught the largest fish or shot the biggest bucks, but I’ve tried. Perhaps you have, too. And that’s the essential thing. Being out there, an active participant in our outdoor world.

I bought a box of 45 ACP Federal Hydoshocks once. It was a 50 round box and when I got it home I noticed someone had exchanged a mixed lot of 7 rounds of various types, manufacturers, and age by how corroded some were. Someone took out enough for a magazine and put their old junk in the box.

[@jonrolfson1686]

Many years ago, for a reason which I no longer recall, I had occasion to open a box of ammo labled .44 WCF at a shop where I was employed. One cartridge caught my eye. When examined closely it was seen to be a .44 Rem Mag rather than a .44 WCF. It seems fortunate that this box was the one that was looked at. If one of our customers had fired one .44 WCF cartridge in a .44 Rem Mag revolver he might have suffered a split case, or only a bad group. One .44 Rem Mag cartridge forced into an old .44 WCF Colt might have made for a bad day.

Yeah, a 0.002-0.004in bigger bullet at 3+ times the pressure... Unless that old 44-40 was built like a howitzer it would have been a really bad day!

I enjoy testing my hand loads, but it does get expensive. Different powders, primers, bullets, and cases. Then once I get it down to a good group, I start testing with Different jump measurements. It boils down to having fun just pulling the trigger and not worrying about the cost. It's a hobby and most hobbies are not cheap anymore.

It looks & sounds like that bolt is pretty gritty?

[@johnknouse8846]

Wilson bought Lehigh Defense. Also, one day at the range last year, the guy next to me was shooting a .270, and complaining his accuracy was garbage. Literally missing the target with some shots. We looked at his scope, rings, and rail, but it wasn’t until a range officer happened to pick up a piece of his brass and notice how weird it looked. Tuned out he was shooting .243 ammo out of his .270!!

How could he not notice that, they are very different length cartridges. How did it even manage to fire?

[@justinbenjamin4651]

That’s crazy! Also, maybe it’s just the camera, but that rifle action sounds super dry and gritty.

[@JamesSmullins]

I noticed the same thing, sounds like it needs some extra oil until it all breaks in.

[@rommelstar1]

My friend once had an odd round mixed in with his brand new 6.5x55 Swedish Mauser ammo. I forget the errant round's caliber, by he unfortunately shot at a deer that season with the oddball round and missed entirely as a giant fireball plume exited his barrel. No harm to the rifle, but it could have been worse.

[@beefcakes27]

According to Erik Cortina, out of the box accuracy is a matter of luck. The relationship between bullet and lands and finding the accuracy nodes (6/1000th's). Of course getting extreme spread through powder selection and volume are essential too. As you mentioned Ron, find what works well enough and just use that. I enjoyed this video. 😊

[@adloutdoors]

Had a similar issue with 7MM. Of all things, there was a 30-30 round in the box. Since then, I inspect and put a sharpie mark to coordinate with the rounds, especially since we shoot a lot of .308 and 6.5. Thanks for the vid!

Same chrono I use... like the app with it to listen to the velocity on my phone. I hear it clear even with ear plugs and ear muffs both in too. Oh gee Ron... glasses and what we see change with em on and with em off!!! Great take on the fouling issue!!! It never ceases to amaze me those who think it dont matter shooting a dirty barrel. When i am doing load development and breaking it in at the same time. I rotate several rifles and start with a fresh clean barrel on each load. Takes a lot of time but well worth it in the long run. Sometimes i will put a higher power scope on a rifle just for load development then when done switch to what I use for hunting. I use my own printed targets and easy to see most bullet holes at 200 yards Thanks for the real world session at the range.. Wow on the 6.5 in a 308 box.!!!! I had a first also not too long ago with different bullets in same box.

[@clintonlayne9253]

Ron I had a box of Remington Core Lok in 22 250 one of the rounds was dented. I pulled the bullet and discarded the powder and brass. I had bought that box of ammo from a store in Yankton, South Dakota . I spoke with the manager and she told me that they are having problems with people removing the ammo from the boxes and stealing a few rounds .The moral of the story is always check your ammunition. My hunting partner bought some Fire line when he went to put it on the reel I looked at it something was odd it looked like a regular Monofilament line . Someone had done the old switcheroo .

[@aaronwilcox6417]

Had this happen where an box of 7mm rem mag had some 7mm Weatherby cartridges in it. Pushed the bolt forward and it was a bit tight on that Rem 700 and it went off before the lugs fully engaged. Got an blast of gas and it buggered up the magazine a bit and my hand took a little beating. Glad I had safe glasses on as I got some in face and all over upper body.

[@murphymmc]

Great job on feeling the "sump'in ain't right" with that ammo change. Most experienced shooters would probably do the same, a shooter with little experience might have run the thing in (if it would go) and fired the shot.

Oooh, interesting topic. There are quite a few of these rounds that will chamber and sorta fire. Some of them are pretty safe, too. Like shooting .40 out of a 10mm. I suspect that the 6.5 Creedmore would have made a mess in the rifle, but not made a mess *of* it.

[@herpderp1662]

40 is a cut 10mm. Both made for the fbi. But since they are limp wristed communist liberals, they couldnt handle the 10, so they introduced the 40.

[@hammerheadms]

USOG told a story of shooting, if memory serves, I think a 30-06 through a .280 Rem. I don't know if they were hand loads or factory, but he mentioned that the bullet stopped at the end of the bore, and got stuck there. Not sure how that happened, but apparently he was able to recover the bullet which had obviously suaged down to the diameter of the bore and clearly lengthened it. I'd say an Angel was looking over his shoulder that day because his face and hands are still intact.

Probably 40 years ago I got one round of .17 Rem in a box of .223 from a store. I just added it to my collection. Not a problem in a .223 but would have been trouble to fire a .223 in a .17 chamber. The bolt might have closed on the .223.

[@DirtRoadGroceryStore]

Butterfly style front bags (bulls bag) will control the hop of the lighter rifle while also allowing it to recoil backward repeatably the same as a heavy rifle does in free recoil shooting.

[@viclemmon9047]

I am so happy that you found that bad round. I glad that you came out on the safe side.

[@jpk818]

A group of us were target shooting a couple of years ago. two of us had 6.5CM rifles and one had a 308. All shooting Hornady whitetails... see where this is going? the friend with the 308 ended up picking up one of the boxes of 6.5CM and proceed to load the mag. fired 3 rounds off and all missed the target... My other friend had a go, and on the second shot got some minor blow back in the face. As he pulled the bolt back the ejector and spring went flying.... needless to say we all learned a lesson that day. Thankfully it hadnt been the other way around.

[@fire_tower]

If the bullet's caliber is less than the barrels you should generally be safe if it does manage to fire.

[@Arcticroberto9376]

That poor barrel isn't going to be doing too good though. I've seen bullets beat up the insides of barrels if the bullet is too small

Crazy story when I got my reloading press I went to de-prime all of my brass I had kept throughout the years, 2 different cases of .223 vmax (kept the brass in the original box) had .204 projectiles in them, one had 3 the other had 2, Im suprised enough powder was even in them to make them go bang or even leave the barrel 😮 correction just looked at some pics and 3 total pieces of brass had 204 projectiles in them, 1 had 1, 1 had 2 and 1 had 3, it was a box of Superformance match 75gr bthp, the projectiles were 32gr vmax .204's

All this expensive fancy hunting rounds might be great in the lab. In the field I know I can depend on the good old Core-Lokt.

[@Nick-wn1xw]

I guess you haven't got the memo. Deer, and all games animals have evolved now and resist all old time bullets. They just shrug off hits with Core-Lokt, Power Point, etc. Funny though the patched round ball still works..... Just ask the "experts" here. Oh and round nosed bullets don't work either. The deer where I live didn't get the memo either so I'm lucky.

[@edwardabrams4972]

The last box I got of Hornaday ammo in 30-06 wouldn’t feed in any of my factory rifles. All 4 are stock rifles🤔😳 so much for quality control!

[@K-bob_45]

Odd scenario. If you’re a handloader and have a headspace comparator you might check that. Typically factory ammo is min spec to ensure it’ll work but it could be above min and you could have a tight chamber. Seems very unlikely that all 4 are min spec. My Winchesters are tight but I don’t think I’ve had ammo that wouldn’t work. A hair of resistance closing the bolt but that’s all

I have the same brand chrono, and when I bought it, I also purchased the lighted bands that are battery-operated.

I agree ron, you should be able to shoot 3 to 5 shots without it opening up too much, i believe caliber and barrel profile plays a big part in that however.

[@richardpiau7546]

Good advice about double checking your ammo! Back in the late 70’s when was a teen-ager, my father and I went to the range. Week before, dad reloaded some .308 for my uncle and mixed up with .30-06 of his gun. I know these 2 rounds have different lengths but he loaded his BSA 30-06 with a .308 by mistake. The BSA was a controled round feed, so the bolt grabed the case by the groove and holded it firmly. He shot it, made such a weird sound and the bullet hit the target side way! You don’t want to do this kind of mistake to oftenly! Fortunately, no dammage. He passed away 10 years ago, but I decided to keep the gun which he bought in the early 50’s. If this gun could talk, it would have so much hunting stories to tell! Thank you so much for your videos, you’re doing such a good job. Richard

[@andymauthe5508]

Ron, as always a great video. Love your no nonsense approach. Question on the NULA. On the video, every time you cycle the bolt it sounds like you’re rubbing two pieces of sandpaper together. I know on your .308 week video, you said that the action was smooth cycling. But it doesn’t sound smooth in the video. Can you comment on that? I realize it’s probably just the way the microphone is picking it up but I was just curious. Keep up the great work!

[@camwinston5248]

Sounds like his jacket rubbing together and across the table .

[@nathanmattern4900]

I noticed the same thing. If you watch him cycle the action it appears notchy as well. Sounds horrific

[@samthai818]

I was working up loads for my .300wby and a guy next to me was having extraction issues with his new-2nd hand 7mm mag. The other ROs directed him to me since I was the target shooting load developing expert at the moment. Apparently this was his first couple of shots. I looked at his box of ammo, and compared it to his extracted brass. Immediately I noticed that the ammo was 7 Rem Mag and the brass came out fireformed to 7Wby shoulders. So basically he was shooting a 7 mm wby rifle with 7rem mag ammo. The shop sold him the rifle and the ammo. A sure way to guarantee repeat business in short order!

[@camojoe83]

One more. Pro tip for the chrono. Usually only useful to shotgun guys, but if you replace the aluminum sticks for the shade screens with chopsticks, you won't have to replace the whole chrony if you hit one.

[@chrisrandall2444]

I had the same thing happen to me years ago. I pulled the trigger on a 7.62x39 in a 243. Luckily I had glasses on and nothing came apart. The copper jacket of the round was lodged in the throat and the lead hit the target. After ram rodding out the case and noticing the head stamp I checked the box and it had about 3 more odd rounds in the box. I always check head stamps now.

About 10 years ago, I got a 270 win in a boxs of 30-06. I did not see it befor I fired it at the target. Low recoil and a bullet that hit the target sideways and far of told me to check the case. There it was a 270 win 😲 in a box of Norma 30-06 target ammo. I broke the seal on the box at the range, so it must have been at the factory the wrong case came from.

Once,when I was a kid my father was shooting my 30-06 and he accidentally put a 243 cartridge from his pocket in my rifle and fired it .the only damage was to the brass .it took about half the cartridge case down the barrel with the bullet and it was very hard to open the bolt and eject what was left of the cartridge.the rifle was fine I went on to take many critters with it .

[@plainairbarnettsoutdoors]

Other than the 6.5 mishap. You are sure shooting lots of different ammo. I usually try to verify ballistics info online to eliminate some that doesn't have my shooting/hunting needs. My pocket isn't as deep as yours

[@jasonbroom7147]

So, the larger case diameter just before the start of the shoulder is what caused the action to be so hard to close, alerting you to a possible problem. Your experience level showed, knowing to open the action back up and figure out what the heck was going on. It probably would have fired from that chamber and maybe nothing really bad would have happened, because the smaller diameter bullet would have likely made its way down the bore without incident. The biggest possible risk was the brass flowing forward under the pressure from being fired, separating just forward of the web and spewing hot gases and unburnt powder back into your action. It's also possible you would have blown the shoulder forward, added more taper to the case, and created a 308 case with a shorter neck. Glad you didn't find out!

Mr. Spomer something that would help in cooling the barrel in between groups and save time. Would be to stand the rifle up in a rack so the heat is allowed to radiate away from the barrel as well as traveling up the barrel as heat would a stove pipe. Also a barrel fan which aren’t expensive and can be made quite easily at home if you were so inclined. A few things Ive adapted myself from long range shooting. Great video again.

I've been hearing a lot of good news about the new remington corlocked tip. Exactly like the old core lock. But it has a polymer tip in the front for extended range. I have actually won competitions with it. Shooting shooting to 440 yd quarter mile. And it was fantastic. For my competition gun shooting in m d t chashi 243 savage. My preferred load is 58 grain Hornady superformance.. Velocity is 3980.. It might be a barrel burner but dang don't it get there quick and accurate. I can keep the group. At the size of a baseball. Out to a quarter of a mile. I chose the 243 because the 65 creed more has the same ballistics out to 800 yd.

[@brandonm6052]

I'm pretty new into my .308 rem 700 sps tactical, so shorter barrel also. I have just shot some cheap FMJ but before deer season I had a couple boxes of Hornady Black .308 168gr a-max. I've tested no other quality ammo in it yet but many guys recommended the heavier grains for this setup and the 168 specifically. It took my first deer a week later with a nearly pinpoint shot albeit not necessarily the right bullet for it. The hornady black a-max can be had around $34-35/box where the precision hunter is more like $47-48. If I had the reloading gear I would start loading some eld-x like in the precision hunter as they say it's a better precision and animal round.

[@prestonmonaghan499]

I remember when my gun club had a chronograph. I took my new Ruger 77 in 30/06 with 150 grain bullets from Federal, Remington, and Winchester. Non of them got the 2900 fps it claimed in the ballistic charts. If i remember correctly, the highest velocity was a little over 2700 feet per second and the lowest velocity was 2389 fps. I started calling my Ruger 77 a 30/30. Funny thing was the brass came out with a big lump on one side of each cartridge case base. I waited for years before i sent it to Ruger for repair. It was a Bicentennial edition that i purchased the day i turned 18 years old. They rebarreled it but i was very disappointed with Ruger after all six of my Ruger rifles had rifling issues. A cleaning rod with a tight patch would stop spinning about halfway through thr barrel for an inch or so then start spinning again. They blamed those "Wilson" barrels. I had several repaired and sold or traded all of them for Winchester Model 70s and CZ 550s. Ive never chronographed any of the new rifles. I frequently think the velocity listed on modern day ammo boxes is very optimistic. Your 308 may really be a 30/30....😮

[@2dResq]

At 26:33 Hornady CX. Put on the earphones, you’ll hear one hell of a ricochet. That’s exactly why I don’t shoot solid bullets. Couple deer seasons ago, a hunter a good 600 yards away shot a buck, the ricochet went right over my head with a good supersonic crack then I heard the pop of the hit then the rifle report. Solid bullets, do not use in areas with other people☠️

[@larrysayers1377]

Really enjoyed this video. Like viewing loads n rifles being tested. Things can happen with factory and handloads from time to time My friend has a Winchester Ultimate Shadow in 270wsm. In Sept (2022) we finally found some factory ammo in Win 150gr Power Points and got 2 boxes. Well in each box one round of 20 would not chamber. Close inspection showed the bullets were seated to different depths. Some were above, some were below the cannelure. Groups were good with the bullets that had the same seating depth or close to it. But as a whole they were all over the place.

[@MIchigan-Savage]

Hornady has been slipping in the QC area lately. Not surprised.

[@vincentstouter449]

Who would believe mixed manufactured ammo caliber in the same box? It makes a good case for always wearing shooter’s safety glasses. 😎

[@yooper7753]

This video proves that even when the headstamp is clearly wrong the cartridge was still chambered. Ron assumed the box of factory Hornady ammunition was correct and safe to shoot. Luckily the rifle made it difficult to chamber the wrong cartridge, so Ron investigated and removed the 6.5 Creedmoor cartridge from the 308 Winchester rifle without attempting to fire it. Years ago Ron Spomer published an article where he chambered a 7mm-08 Remington cartridge in a Dakota model 10 25-06 Remington rifle and fired it. Ron and the rifle were OK, but proper headstamp didn't prevent that incident. I say this because I'm a 30+ year reloader and I use different parent cartridge brass to makes other cartridges. I use 7.62x51 Nato/308 Winchester brass to make 7mm-08 Remington and 338 Federal ammunition. I also use 30-06 Springfield brass to make 338-06 A-Square ammunition. Doing this saves me hundreds of dollars in money versus purchasing proper headstamp brass or ammunition. Some people in social media platforms and online forums give me corrections because they feel my ammunition is unsafe because of the wrong headstamp. I tell them I have a great system of labeling and documentation and it has never failed me yet. I simply dismiss their concerns. End result is even with proper headstamp ammunition doesn't automatically mean a person won't make a mistake.

[@carterthiessen2664]

I had a box of 270 130gr core lokt that had one round stamped 35 whelen, but it was definitely a 270 round. I compared its dimensions with the rest of the 270 ammo and it matched so I just ended up shooting it anyway. In hindsight I shouldn't have, but oh well.

I found a 30-06, which was clearly .308 caliber, in a box of .270 Win Core Lokt while I was about to load it into my magazine. Ever since that day I always look at all the head stamps before loading them.

[@camwinston5248]

You both probably already know..3006,270,and 35whelen are all cousins based of the 3006 case.

[@daleplant5275]

Glad that round jammed on you so you knew not to fire it off. I know 308 not your favorite but I am considering it as I will only be buying one rifle. Hunting in New Brunswick, Canada for moose, deer and bear. I do not have budget for more and I am thinking that buying 7.62 Nato for practice is the way to go. I am a disabled hunter and also considering the 270 Win as I expect to be taking shots across fields up to 400 yards.

[@tlloyd9325]

I once shot my son’s 270 bullet out of my 280. Easy 50+ yard shot but it sounded and felt weird. Realized what I had done then back to my truck to get MY ammo. After an hour of tracking found him and finished him but it took two shots. First one went ??? the second one did the job. It didn’t damage my rifle but took HOURS to clean the bore. Since then different colored boxes for different calibers.

Head stamps and barrel stamps can and will be wrong. Fella bought a 7mm- 08, tje barrel blank was .308 from the manufacturer. 243 Winchester with a 308 stamp from the factory. Dimensions 243, head stamp 308. Witnessed them both.

Ron , it would have been interesting to see how the 6.5 shot out of a 308....barrel....also how the 6.5 brass would form itself to the 308 chamber...

I accidentally shot a .270 out of my 7mm rem mag. It fire formed the case and ruptured it at the based. The debris damaged my lenses on my glasses. It would have taken my eye out if I wasn't wearing them. From the sound I knew something was wrong. When I bolted the gun and grabbed the case it was hot enough to burn the hands. Scary situation!

[@rickeycooley9139]

@@stevenstone9272I went to range with a.308 and .260 . I started with the.308 rifle. Now both are model 7 Rem. They look the same, Identical. I loaded the model 7 .308 with.260 thank God I loaded that way . I shot 3 rounds check it. I almost fainted when I saw the target. What would’ve had I had of started with the.260 and put the .308 in the.260. Blow up. I’m a lot more careful now. No problem, but I learned a real good lesson.

I had a 6.5CM round in a box of Federal Premium 168gr Sierra MatchKing about a year ago. That was a first for me too. But you probably have me beat by 1,000,000 rounds.

Perhaps ammunition ammunition suppliers should consider clear sticker each end to show it is factory sealed and indicates no-one opened box before you.

Wow. I've had this happen with 223. I grabbed a few boxes off the store shelf not realizing that two boxes of 222 was mixed in. I catch the error about 2 weeks later.

It may just not like the seating depth of these factory loads, granted they’ll vary but NULA may have used a reamer with quite few thou difference than average.

Wilson Combat now own Lehigh Defence.

[@BeaterJeep]

Had this happen with a 7mm08 in an off the shelf box of 308… it chambered and fired. It sounded strange - a sound that can’t be described in print; like an object going down a pipe similar to a low toned thuwump…… probably a lack of pressure. I’m sure some clown compared them and mixed it up. Lesson learned 25 years ago. Still have the brass.

[@jfess1911]

Ron is lucky that the 6.5 CM didn't jam in the chamber. It does indeed have less taper than the 308, so it can jam tightly if someone tries to force it.

[@Chuck1284-]

I once fired a 243 in a 270 by mistake, ammo was in a ziplock bag and there was a mixup. Weird report and didn't see the round hit anywhere on the dirt berm, thought it was a squib. Bore was clear but the casing looked odd with a short, lopsided neck. Nearly vapor locked when I saw the casehead "243 NORMA". Cheated death again! Now I'm very careful to visually inspect ALL my cartridges at the range and before I hunt, that $hit makes a believer out of you.

[@whillhern]

I fired a 7rem mag in a 300 win mag once, no harm except the bullet hit the paper sideways at 100yds.

[@buddywaters9427]

Ron I had that happened to me with a box of rem. 308 one side of the box was 243 when I shot the recoil and noise was a lot less I carried the remaining ammo back and the store gave me another box

Wilson bought Lehigh, so yes, they like the Lehigh ammo. 🙂

I always enjoy your video's . The discussions and tests you do I find interesting . Thank you

[@davidrose415]

That is something you should call Hornaday about. How it happened on your end doesn't matter. It happened. That makes it an issue they need to discuss with employees. Had a young kid got that box by some means they probably would have pulled the trigger. The difference is enough that the bullet probably would wedge in the barrel, and could have blown an entry level rifle up in a kids face. So it is a conversation that Hornaday needs to have with all of their employees. Not a hypothetical conversation like they have in training, a this box got out of our factory conversation.

[@MIKESTREED]

Its like throwing a hotdog down a hallway! 😂

[@Big_T51]

Love the .308 content

[@russellmerritt9935]

A buddy at the range shot one of my .264 round through his 338 by mistake. It was very muffled and the only thing that happened was that it expanded my brass to 33 caliber and I couldn't resize it that far. A 6.5 Creedmore through a 308 should be about the same. A deal danger is firing a 308 through a 30-06. The brass would most likely split and gas blow back could happen. This could readily happen on a Mauser style controlled feed action.

[@hammerheadms]

I did some testing of new ammo for my .270 Win this deer season, since my regular Federal Fusion has not been available for it. I tested Winchester Deer Season cup and core, which grouped well, but the Hornady Outfitter CX loads in 130gr. did something unexpected. The first shot keyholed, and the subsequent two follow up shots were not even on paper. I can't figure out why, but I did notice a lot more copper fouling (more than I have ever seen before) in the bore when I cleaned it after getting home. For the record I shot the all copper loads first, and the Winchester cup and core after. Really disappointed in the CX bullets performance, but I can't help but wonder if it's my rifle that's the problem. I cannot shoot 150gr. bullets in this rifle. They TOO keyhole. 130-140 grain, no problem. I have heard that your typical all copper bullet is longer than your typical jacketed bullet at the same weight because copper is lighter than lead, but an odd thing I noticed after the fact is that the 130gr. Winchester Deer Season ammo STILL has a higher ballistic coefficient the the 130gr. Hornady CX ammo. This is all very maddening! Can someone please tell me what I am missing here? The rifle is supposed to be 1:10 twist, but the results I am getting make me think someone at Remington is lying about the twist rate. Is this just a common problem with all copper bullets? I suspect the 150gr. bullet instability is not an uncommon problem in .270 Winchester seeing as I have heard other folks reporting similar instabilities when they fire 150gr. pills from some rifles, but now the 130gr. all copper bullets behaving in similar fashion...??? On a side note, I have found a 30-06 cartridge in a box of .270 Win Core Lokt ammo. Lucky for me I saw the head stamp as I was loading it into my magazine, so no harm no foul. Checking your head stamps is great advice. This lack of quality control is not uncommon for factory ammo, no matter who manufacturers it. Be safe out there, y'all.

[@larsstefanaxelsson]

Well, its easy to check twist rate. All you need is a ruler and a cleaning rod (with a rotating handle). Just tape a flag on the cleaning rod, measure distance, push the rod in (jag with patch is best) until the flag has rotated one revolution, measure again and see what the distance between the measurements are. That’s what I’d start with to actually confirm the twist rate. Then, indeed copper bullets are lighter for their length, and stability is mainly about length, so you typically cannot shoot as heavy lead free bullets as you can lead. There are many stability calculators on the web where you can input the bullet, caliber twist rate etc. and see if your bullet is stable, at least in theory. Just google bullet stability calculator (the Bison bullets one is good.) They’re good enough regardless of bullet material. And I’m no 270 shooter, but not stabilising 150gr bullets sounds wrong to my ears. There’s something funny going on here…

[@hammerheadms]

@@larsstefanaxelsson the rifle nomenclature says it's 1:10 twist, but this is also a Remington from a very sketchy era before bankruptcy. The rifle shoots lights out with Federal and Winchester 130gr. jacketed ammo. Anything heavier than that won't group onto a dinner plate. I am at a point where I'm inclined to agree that it might be the rifle.
