Best reloading channel on the planet. Love it

[@just1more621]

Amen to that.

[@nelsonbutcher1]

Power Pro Varmint is my fave 223 powder. I have seen it push the Hornady 75gr bthp to an eye-watering 2930fps and no pressure signs out of a 20 inch tube. I forget the load and dont remember it being exceptionally accurate. I never went higher as the speed was starting to worry me. Theres just something about the pressure curve in that powder that makes it hold pressure longer i guess and it makes it awesome for hot-roding 223 if you have the stones lol.

[@Thorsaxe777]

Johnny, excellent work once again, Although life on KZbin has gotten harder for channels like yours, You have attained the integrity of the foundation of your very first video, "Provide quality content" and you have not wavered in your commitment to your viewers. this show with every video you produce. The primary objective of your video content is to show the science of reloading, thus producing the positive and negative results to the viewing audience. many people out there don't understand that this is not mostly about entertainment or what is new this week. many Match shooters and professional marksman watch your show and appreciate the level of your testing and evaluation of products. bullets, primers, brass and reloading accessories. Thank you for your Years of service to the firearm community. Dave

[@THutch556]

Great Shooting JRB, I have shot a lot of that N140 load of 24.1 grains with CCI 41’s as a generic accuracy load when shooting different riffles out at the range, as that is the “Accuracy load” Sierra recommends in their Reloading Manuel for the 77 grain SMK and tends to shoot really well in most all rifles. It also shoots .5 in my 18” WOA if I’m doing my part. I figured velocity wouldn’t get there with N140 as charge weights and burn rates are really close to Varget, but excellent accuracy. Nicely done. I haven’t tried Power pro Varmint or 2000MR yet, I have been happy though with 25.2 grains of 2520 for my MK262 clone load, so far it’s been really good. But after seeing this I may have to pick up a pound or two of Power pro Varmint and 2000MR to try. Thanks for the great vids, I know you have a million things on the table for vids, but if you ever get caught up, I would love to see the 73 grain Berger HPBT target bullet tested in your .223 series, as many of my shooting buddies are having great luck with that bullet in the factory Federal GMM Berger ammo. I’m thinking it would really shine with N140 or 8208 XBR. Also any Match bullet testing in the 6.5 TC Compass would be great. Either way, great stuff and keep up the great work. Glad to see you posting Vids a little more regular again. Thanks.

[@andygrew4832]

I really enjoy the Mk262 series, thank you.

[@ashleypalmer7983]

Since you’ve covered so many different powder combos, perhaps we need a summary. Take the ones that match (within 50 fps) of the Mk262 ammo and reshoot to verify. Even if they don’t group as well in your rifle, they might group in someone else’s.

[@JohnnysReloadingBench]

We did that back in Video #10: kzbin.info/www/bejne/m6jIkploe62poZo There will be more videos like that in the future. Especially now that N540 and Varmint have proven themselves over the last couple videos.

[@jpenna1976]

@@JohnnysReloadingBench Regards from Finland! Nice to see our Vihtavuori doing well. Also, our powder selection is pretty much limited into Vihtavuori and others are available rarely and probably not the one you are exactly looking for. But, the question... N140 or N540 better to get best of 16" barrel? CCI 41 is not available here, but CCI 400 is everywhere and 450 is pretty easy to find also. Which one would be better bet?

[@ryanfilter7545]

@@JohnnysReloadingBench Hey Johnny how often do you deep clean your bore?And by that I mean decopper and scrub the bore as opposed to just maybe just running a couple CLP covered patchs down the bore after a range trip to take care of carbon.

[@fredmeebley]

@@jpenna1976 cci41 is probably closest to cci450

[@johnpa9326]

@@jpenna1976 I see you posted the question over a year ago…. I called CCI awhile back and asked what the difference was between their small rifle primers. I was told that CCI *41 is a CCI 450 (magnum) with a thicker cup and the anvil was a different shape, everything else was the same as the 450. I have never purchased 450, almost all my small rifle primers that I shoot are 400 or *41. When I’m loading extruded powders I use 400, when loading spherical ball powders I use the *41. In past load development when using H335 or w748 my groups shrank in size after I switched from 400 to the *41’s.

[@jamest2168]

Awesome video as always man. Thanks!

[@allenstephenson3554]

I understand this is an older session and do enjoy seeing your load data. I have always heard that verticle is a powder issue and horizontal dispersion is seating depth or wind conditions. Some of your groups I think can be tightened up some even with the magazine limit if you adjust seating depth. Good luck and keep up the good work.

[@BuntMeister66]

Great video again, and Nice, 224 Valkyrie, just bought a 224 barrel and some Starline food too...

That was some crazy velocity with the pp varmint. I might just have to try some of that out of my new stag rifle

[@TrumpsEarBandage]

My favorite series on the channel, aside from the upcoming ar10 series 😃😃

[@nickrussell5150]

Love your channel. Its like movie night for me.

[@garysnyder527]

May not be important but I tested over half of what you tested and found XBR to be the cleanest burning.

[@benjaminbrown1179]

Well well well......... Thank you for not pussing out on the max charge, and sending them down range. Proves to us all that You Tube didn't get your nuts!!!..... I'm ready for some new barrel ar 10, and damn ready for the 6.5 Creed!!.... Get back inside, in the cool, and keep them coming.

[@ewetho]

Benjamin Brown .... Yup send 'em... Hey Johnny.. think of it this way... Pressure is only one component of how fast a bullet goes down the barrel. Heat is another variable. Pair the burn temp and burn rate and that would tend to determine the rate of production of gas. Slow but rate and high temp would probably give you a much broader pressure curve as a fast powder much more of a spike. So powders such as Reloder 26 give very scary velocity but not necessarily dangerous pressure. But it will still burn a barrel. Don't think you were in danger, but if you ran some strings of fire it might get hotter faster.

[@richardtibbetts5020]

Got a few good groups..good vid!

[@tires2burn]

I like your videos a lot. I need some info from you. Can you run a video of loading test rounds and your way of keeping track of all the different loads before you go to the range.. The way I am doing it seems lame and you always seem to be organized when your testing. If you have already done this let me know what one to watch. Thanks and keep up the great videos.

[@WestDesertShooter]

Wow man so much great content. I may have to get some power pro varmint to try in my 24” barrel and push for some crazy velocities! Also great stuff coming up, looking forward to it!

[@reloadeverything8695]

I knew we would get a vid today I been waiting jonesing thank goodness I was hoping for 223 vid as well I wonder if we'll get a 6.5 creedmoor vid next to passing us while we wait for more build and test vids

[@JohnnysReloadingBench]

That's a good possibility. I discuss what's coming at the end of this vid, but don't be surprised to see a 6.5 Creedmoor video come out of nowhere. I've got at least a couple more videos I want to make with the T/C Compass before we switch to the AR-10, so that will be happening very soon. I need to go back and look what still needs tested in the compass. There are a bunch of bullets we haven't touched yet.

[@paulharveu526]

I know the N140 didn't hit the velocity of Mk262, but the velocity wasn't bad, and every load shot great, to the same point. That is a dang fine combo.

[@itvnz]

Would love to see Varmint groups for 24.6 through to 25.0 Johnny you've a genius for trying this powder with this weight of projectile.

[@JayDee-bz2ge]

Not sure if anyone noticed, but on that 2nd crimp, you can see the press flex. Probably deflection in the rotation mechanism. I'd like to see a dial indicator test between reloading presses, see what's what. It's a easy few thousands , probably where your over length is coming from, maybe...

[@garysnyder4912]

Sure wish you would give us an up-to-date video of the best combination, with if possible duplicate results, Please.

[@theironroad5502]

Any chance you'll ever do a load development this intense for the 77gr TMK???

[@jordanhays732]

Try the same powders you did in this video for the 224 Valkyrie with the 77gr tipped MatchKing. That is something I would love to see.

[@cratxn1]

Have you tried a long drop tube or a swirl funnel pour for your compressed powder charging ? Why not a brass catcher with the bottom zipper open to keep your brass where you want it ?

Thank you for all the time dedicated to these videos. I have watched most all of them and the amount of information is overwhelming. Therefore, please advise. If you were going to load 1,000 rounds for S.H.T.F. ammo, what would be the recipe to date. 77 grain Sierra M.K. , #41 primer, L.C. brass trimmed to 1.760 " COAL ? powder ? charge ?

[@creekmiata]

My Lee seating die fits the 77 SMK perfectly.

Hey Johnny, you ever test IMI Razor Core 5.56 w/ 77SMKs? I measured it using my Caldwell Chrono and I was seeing an average of 2841 FPS out of my 18" SS barrel. Out of my 20" SS barrel I saw 2855 FPS. I guess the Israelis aren't worried about pressure. After watching your videos I should probably had a close look at my brass. Hah.

[@dlim4325]

You said you wanted to find an extruded low temperature sensitive powder? What about IMR 4166 at about 23 grains? Its in the burn rate wheel house and is an Enduron powder.

Johnny bring on the Valkrie and the starline brass pal. 90gr sierra with TAC?

[@ericwilliams2317]

I'm not too sure why you gave the thumbs up to the "Varmint" powder and a thumbs down to the "N140". Judging by the groups you put together N140 was way ahead of Varmint. Speed isn't everything - whereas, accuracy is. I'd prefer to hit slowly than to miss quickly.

[@G5Hohn]

PP varmint has no heavier bullet data because the marketing people at atk decided it’s a “varmint “ powder only at thus only for use with lighter bullets in .223. I think it’s just a hair faster than PP2k

Just curious if you've ever used N140 in 6.5 Grendel or heard of anyone using it for that by any chance??? I ran across a few pounds of it for a really good price and it looks like it's in the burn rate for the Grendel so was just wondering because I couldn't really find a lot of load data for it...

[@lukepippin4781]

Is it normal to find ejector marks and whatnot on range pickup brass from factory ammunition? Seems like so much of the brass I find already has pressure signs.

[@desertfox2020]

I've seen ejector swipes on much of the factory M193 I've fired

[@HIinfidel]

Are you using a small base die still? Are you ever worried about over working the brass?

Is there any way to actually get the chamber pressures via testing equipment?

[@talkingrock7011]

Have you tried H4831 SC with the 200 grain MK in your 300 WM

[@TreborUSCG]

I never noticed it before, but Vit's reloading data shows 2652 FPS with 24.7 grains of N140 from their 25" barrel!! Your showing 64 FPS faster with a barrel 7 inches shorter!! Just Wow. Your barrel doesn't seem particularly faster when looking at other powder charges you've tried, so that increase in FPS with a shorter barrel is rather startling. Thanks for all your efforts.

why at 25.1 gr of Varmint did your POI shift to the right? great group at 24.8 gr

[@JohnnysReloadingBench]

I'm not sure. You see the same thing with N140. The POI shifts from left to right as velocity increases. I guess that's just barrel harmonics at work or whatever!

[@ewetho]

Johnny's Reloading Bench refresh my memory...did the other upper exhibit that behavior?.. If not the Valkerie may still have exasperated a flaw the .223/5.56 may not fully reveal. Maybe we should get you to lap the barrel socket like you did on the AR10........edit... Just looked back a video and the AA2520 blew open to the right as well....hmmmmmm... Might actually be just starting to reveal an issue.

[@jeffrice1114]

do you have a level in,on scope or scope mounts? Have you taken the temp. of barrel when you have shot several rounds or shoot till you cant touch it? I have watched a lot of your videos, not all of them because I have been reloading for 36 years and some just don't interest me. But lately I've been getting in to .223 ar's, always have had rifles in .223. There seems to be something wrong with your setup. I was hoping the white oak barrel shot better but I still see the same patterns, it might shoot a smaller group when things come together but there is some thing is just not right. If it was me for all money you put down range you should buy a top of the line barrel krieger or Bartline I'm trying a new battle arms development this weekend until my krieger gets here in a few months and put that one on and see the difference. still some good vel. info. Thanks

[@AgileK9TopDog]

[@JayJay3Fifty7]

AgileK9TopDog Seriously, I think, the 224 Valkyrie has less recoil, more downrange energy and bucks the wind better, I'd go with the 224 Valkyrie. I heard Sierra bullets made a 95gr SMKs and can't wait to see what 224 Valkyrie will do with it.

[@notrubd]

Have you shot the TMK version? I was thinking i would send you some.

[@TrumpsEarBandage]

Johnny's Reloading Bench the 69 tmk is .982 in length and can be loaded mag length safely. The 77’s are 1.072 and can lead to some pretty high pressures at mag length. DONT BLOW YOUR FACE OFF

[@notrubd]

Johnny's Reloading Bench - Well I have a new box of BlackHills 5.56 77gr TMK. I can send you some of the rounds and next video maybe you can shoot a couple groups. I know its not the OTM version but it would be interesting to see if they are as good and with similar FPS. I will send enough for you to measure and take apart as well as shoot. If you think you would like to try a few reloads I'll gladly send a box of the bullets at a later date .

[@JohnnysReloadingBench]

Ahhh...I follow now. Factory ammo didn't even cross my mind. Sorry for the confusion. Yeah...if you wanted to send a few of the factory rounds along to test that would be great! I'd love to see if Black Hills matches the velocity of the standard rounds.

[@ccw22lr]

It's my understanding that the 77TMK's ogive is optimized for ARs seated at mag length

[@jantonie420]

Are all these shots at 100 yds

[@calangel]

Those pressure sign differences are due to the differences in the burn curve between typical single base, extruded powders that control burn rate with geometry and light coatings, and double based, spherical powders with heavier deterrent coatings. Spherical powders start "slower" and have fatter "tails" on the burn curve. Nitroglycerin also alow for higher velocity at any given pressure. Total area under the burn curve and gas volume is what drives velocity--NOT peak pressure. Why is this so hard for reloaders to understand? PPV was not way over pressure...N140 was over pressure at way less velocity, which is proof that you assertion about muzzle velocity is wrong.

[@themobsprinter]

I'm a new reloader and just started reloading my first .223. I've read that if you use 5.56 brass you'll want to use less powder than a .223 case due to thicker walls. Is there any truth to that? And if so, by how much should I decrease my powder load? All answers are appreciated.

[@themobsprinter]

240FP Thanks. Trying to load up some .223 soft points for deer season and the last thing I'd want is a nice big buck walking into my sights and my gun blowing up when I pull the trigger. I finally got my last bit of equipment last week so I'm trying to stay as safe as possible. Thanks for your help.

[@themobsprinter]

240FP Thanks. Have you ever used the Lee quick trim? I've been trying to use it myself, but regardless of my actions it will not trim my brass. The vast majority of my brass needs trimmed so that creates a big problem. Have you ever heard of that problem or how to fix it? If not, what would be a high quality affordable trimmer for .223?

[@themobsprinter]

240FP Thank you. I'm pretty close to throwing my box of resized .223 brass across the room because all I want is 100 pieces to load for deer season and I swear they grow out of spec when I touch them haha. All I reload at the moment is .223/5.56 and 9mm, but I hope to get into .308 someday. No reliable source of brass and I can't afford to shoot .308 all day to make brass. My range is a little wooded area several miles outside of my town, so that eliminates range pickups as well. I'm sure I'll find some eventually haha.

[@themobsprinter]

240FP That figures. Reminds me of when a friend asked me what caliber of pistol he should buy. I said to buy a 9mm or a .45, and pushed the 9mm so I could have a source of brass to reload. Now almost a year later I have half a 5 gallon bucket full and more keeps coming. Need to figure out how to build a teleporter so you can send me all that .308 brass you're not using. Guys that shoot with me have given me the nickname Brasshole. I'm not leaving until I've picked up every bit of brass. I don't care if it's .22 I'm picking up every bit of it lol.

[@DwnRange]

In this instance, the OAL is dictated by the AR15 magazine.

[@LKN4WAR]

This was based on the OAL of the Blackhills 262. A bit shorter than the usual book recommendations for magazines. 2.260” in the current Sierra Manual

[@joshhuttunen8821]

I'd like to see a video on 69grain tmk

[@johnsenuta1038]

H4895 is a better powder for the 77gn.

[@JohnnysReloadingBench]

Define "better". We tested H4895 a little in Video #10 but I need to go back and try it again. Same with Reloder 15. I chose the wrong charge weights with both and had pressure problems. I don't think either powder will be able to hit our 2760 target velocity. Great accuracy powders, though.

[@TimKollat]

I didn't see anything that I would say were pressure signs on your max varmint charge..none at all. if you are saying you were way over pressure with the power pro varmint but yet seeing no pressure signs on your brass, then looking for pressure signs on brass is useless. Obviously if your brass doesn't even have flattened primers, you weren't having any pressure problems. if you REALLY want to read your pressure you need the equipment that will tell you the PSI or CUP readings. I don't know what you are afraid of with the power pro and those 2800 fps velocities. Ive gotten just over 2800 with TAC but out of a 20" barrel. Id keep on going and see what 2900fps looks like and see if you get another accuracy node. That would be a killer round at 2900fps and less than an inch group. If your brass is fine, you're pressure is fine. The whole "blowing up in your face" thing due to a little too much powder is complete horse poo, internet rumors. Explosions are always from obstructions or an idiot reloader that used pistol powder for a rifle load.

I meant to also add that your data on PP Varmint show how incredibly bad Alliant is at testing and marketing their own powders. It's like they don't care whether they sell any or not. Not testing PP Varmint with bullets heavier than 55 grains, when it's burning rate is notably slower than their own AR-Comp is inexcusable. Also not having any 5.56 Data when 5.56 & 223 Wylde chambered rifles are among the most popular sold and reloaded for in the USA is also puzzling. Do they even get out into the real world with actual shooters and reloaders?? You know the real customers that might buy their stuff if they actually spent some effort testing and marketing their powders....
