"A smart man learns from his own mistakes, a wise man learns from other peoples mistakes" Thank you for the great videos Johnny, I always learn something when watching!

[@gregrichardson2528]

Thanks for some July 4th JRB. Something to watch while drinking a beer and waiting on the grill.

[@otetechie]

This is the quality content I love from this Chanel. I had no idea what he did wrong until he explained it. I would have screwed up my brass and had no idea how to fix it. I learn far more from the videos where he shows his mistakes than the Chanel’s that edit the videos to only show things going right.

Merica! Johnny your back! Happy 4th! Good to see another 308. I wonder when your gonna try the hornady A tip.....

[@clinkerclint]

This video was randomly suggested to me from YT. We sure do miss ya Johnny.

[@NorthwoodsNomad]

I don’t know much about reloading, but that’s why I’m here , just trying to learn more before I honor amd buy a bunch of stuff that I don’t know anything about. You just shared some great knowledge, and a learning experience about the flash hole ( something to be aware of as I don’t want to make those costly mistakes) Great content ! I enjoy your videos and I look forward to seeing more . Subscribed !

Wow WTF no notification, was just looking around while watching a video and 1 hour ago JRB loaded this...hmmm lol Hey Johnny! My 4th is complete. Just need to get some firecrackers now!

[@ironbomb6753]

I'm just starting to get my Palmetto State AR10 warmed up. My rifle has a long jump to rifling, this video gives me some opitimism that I might get small groups too. Not as good as these, but under an inch would be awesome. I love these videos, 👍👍👍♥️🇺🇸🇺🇸🇺🇸🇺🇸

New jrb on the 4th of July, just awesome

[@GreenIris1110]

[@rdsii64]

I finally got my AR10 video fix. Great job as always. 8208 is all I use in mine. My barrel likes 155's the best. It will shoot heavier weights ok, just not as good as 155's.

[@jasonhughes63]

Havent seen any notifications for this channel in a while so i searched for it to find the new vids. Glad to see you are still with us, too bad it isnt showing up in my feeds. BTW I love the new gamechangers, im gonna be converting all my hunting loads to this bullet. I had spectacular results on deer last year in my compass 30-06.

[@tw9676]

I had good luck with the eld x bullets last deer season but I'm interested in the game changers if you keep doing more videos on them.

[@MrJegjr]

In my experience, Primer pocket reamer is useful when using military cases, as the primers have a crimp.

[@desertfox2020]

Yeah, most of my 7.62 NATO brass needed reamed before I could prime them. I could force some, others the primer actually got deformed.... which is a little scary

[@WARLOK813]

@@desertfox2020 the rcbs military crimp remover works great for the crimped brass. Wont make your primer pocket sloppy and priming is a dream when your done.

[@keith9737]

New JRB! Awesome! Love watching you work through mistakes. It's the best part of the channel. I don't shoot 308, 6.5 CM, or 300 BLK, but I've watched them all. Don't forget to lube your decapping pin when you go to enlarge the last 10 flash holes. 😁

Love the game changers, 44.4 gr of varget with base to ogive of 2.130", group size is .227 for a 3 shot, 65 deg. F. Best hunting bullet yet.

[@101soviet]

44.5 of Varget or IMR 4064

[@Dave-cf2ng]

i have been switching to Peterson brass from lapua. I am very impressed with their brass

[@AkA-me-Kenny2]

Another video that makes me envious of those groups! FYI, Hornady sells a flatbase/attachment for the calibers. I've counterbored/relieved the center so that any extruded primer does not touch. Thus when measuring base to datum, I get no interference from a high primer or any extruded material. I also added an extension to the modified case measurement tool, so now it can be used on the AR10. .

[@PC-vq5ud]

just use your empty hand priming tool and reseat any primers on cases you want to measure, it pushes them out of the way.

[@garysnyder527]

Hope you are having a fantastic 4th of july. Thanks for all you do.

[@320fullclip]

I’d like to see a 3 part series starting with your standard format of essentially finding the optimum charge weight. Then a video on overall length testing. Then a video testing different primers. Maybe do it with your new 223 bolt gun........:)

[@freedomfirst5420]

We always learn a lot from you, especially when you make mistakes!👍👍 Great video's!

[@skeezixzx9r]

Thank goodness you are back! Missed you sir!

[@caseroj6020]

Cool video. I settled on the Sierra TGK 165 grain in .308 for reloading my 308 Win cartridges. The 180 grain Norma Bondstrike bullets I got seem like too much for a 308 Win case so I reserved those for my 300 Win Mag and 30-06 Sprg case reloads whenever I get around to starting them. Thanks for sharing and posting.

[@mrhangfire1]

The primer pocket reamers do a great job cutting out primer crimps on NATO brass. I've gone from swaging to just reaming them.

[@JAM4MORE]

Yes another 308. Miss the 300 blackouts. Would love to see some 9mm carbine loads

[@Alex-gi7sm]

Comment on 7:50: I needed a primer pocket reemer in order to reuse Hornady .308 brass from factory ammunition (Full Boar, Custom Lite, American Whitetail,...). The pockets were to tight for standard large rifle primers like CCI200.

[@circuit_stu]

Great video! Looking forward to the next GameChanger v. GameKing video.

[@anthonybrown2989]

I would like to see more of the .308 tgk. Happy 4th!

[@243Outdoors]

8208 has been catching my attention, I may have to find some.

[@JPsaysno]

Yes sir. Great powder for 223 with heavies as well. My 22-250 likes it as well. Good luck on your verture.

[@SlavGuns]

8208 is a fantastically consistent powder! It is a bit harsher of a recoil than say reloder 15 but well worth it! Particularly for 308. Just did the video of it shooting sub 1/2 moa in TC LRR 308.

[@tmurray1972]

The Lyman primer pocket reamers that come with the orange case prep multi tool, are for removing military primer crimps. I have used the small one on 223 and it works pretty good. I also bought the small decapping pins .054 with my Mighty Armory shorty bull die, I think the .054 would have cleared the flash holes no problem.

[@jeremycomtois6550]

Velocity , SD , ES comparison between the good brass vs the extra large flash hole will be interesting

[@th9797]

Hi Johnny, I have good results using a mandrel die to uniform and round out necks, you may like them as well.

[@MrCharley201]

Good video Johnny. I would like to see you try the Nosler 165 gr. ballistic tip bullet. I have had good success with them in my bolt guns.

[@PC-vq5ud]

I have shot some good groups with the Ballistic Tips. They are made as hunting bullets, not match bullets. Many hunters have told me that they do not get good results on medium game. They have had to track their animals more than other hunting bullets. If you hunt and want Nosler use their Accubond or Partition bullets. Both kill reliably.

[@MrCharley201]

@@PC-vq5ud I am a avid deer hunter. I have taken many whitetail deer with ballistic tip bullets. Deer up to 200 lbs. out to 300 yards. Never lost one, but a few went a short distance before falling. The partition bullet is for larger game like moose and elk. They do not expand well on whitetail deer.

[@PC-vq5ud]

@@MrCharley201 Glad to hear your results. Just goes to show that experience is the best teacher.

[@gravewhite1258]

I appreciate so much that you own your mistakes.

[@dwaynewood8156]

That 41.6 group is good to see that’s your scatter group drop1.5% from that which is .6 g that gives you 41g that’s your low node will shoot good than go up .6 from there that’s your high node will shoot goo there to adjust seating depth if needed love the videos John keep on shooting don’t blow your face off brother 😂👍

[@FullSendPrecision]

I sometimes see the last shot out of a gas gun leave the group as well.... I think it might have something to do with the bolt locking back... changes the harmonics of the gun. I'm going to try shooting 5 shot groups with a dummy round in the bottom of the mag so the bolt cycles

[@JAM4MORE]

Interesting. I would be curious about that one. You might be on to something. Happy 4th

[@JAM4MORE]

@Ivan Karamazov i was wonder about that.

[@FullSendPrecision]

Ivan Karamazov maybe. But the bolt will close differently without more ammo in the mag below it creating drag.

[@johnisgoodjohnisgreat5449]

This is by far my favorite powder for 308. I pair it with a 175 SMK though, and the results speak for themselves

[@rmbettac]

D’oh! These are great results, though! Very interesting how well they both performed with that much freebore.

[@theslingandjacket2337]

Great vid! Hard to go wrong with 308 Lapua Palma SR, Sierra, and 8208...👍. One thing for people to consider is that the SR primer is not a good option in larger cases for hunting in regions with cold temps. Anything below 40F and it’s wise to use LR primer brass (both in 6.5 CM and 308) to ensure reliable ignition.

[@ewetho]

At least until you put the large diameter primer decapper through it l, LOL .. uggghhhhh!

[@neilswemmer38]

For cleaning of your brass after sizing, chuck all your brass in acetone and take them out, and its clean in seconds

[@sylviacandler5541]

In my Krieger bbl on Rem 700, these 165g TGK like to be seated very close to the lands, if not barely touching the lands. Tiny groups are the result from barely touching the lands. I have a "Palma" chamber in my Krieger that has a short freebore, perfect for these kinds of bullets, also the 155g TMK also shoots tiny groups. Also, best accuracy was right at a max load, and I am using Lapua brass. Primer brands do matter when trying to achieve very small groups.

[@reloader7sixtwo]

A long bullet jump doesn't always translate to bad groups.

[@jonjames4281]

Sweet vid, so it looks like those GC bullets might work out, love that 8208. Thanks. would love to see some hornady 178gr eld-x out of the 308, bullet looks very interesting to me.

[@ronduncan8627]

Good information on the Game Changer. Just bought some to try out. My 308 AR-10 with 168g Match Kings, shoots really tight groups using 42.2g of RE-15 (less then one inch out of a mid range priced AR-10). Yet I have not had close to the same results with Game Kings. Since the Game Changer bullet is closer to the Match King in design I'm hoping to see some tighter groups with it.

[@turbosandmagnums771]

Good stuff. Happy 4th 🇺🇸

[@ssswdon]

Those aero upper/lower are sweet

[@sylviacandler5541]

In my rifle with short freebore, the Tipped 165g Game king shoots a bug hole group WHEN seated very close to the lands with several different powders, IMR 8208, H4895, Ball C2, Benchmark, and R15. With the long freebore factory rifle, the standard NON vld type of bullets, 150g Hornady btsp, 165g Sierra btsp, shoots bug hole groups also jumping quite a ways. I am leary of shooting a vld bullet in a long freebore chamber which will take some trial and error. The Hornady 165g BTSP should not be over looked as one heck of a good killing bullet on large deer and hogs. For extreme cold weather, I have reamed out the small flash hole brass to a large flash hole which fixes any of the hang fire issues with no effect on group size.

[@Clarkecars]

Happy Independence Day and S/F!

[@WARLOK813]

Nice to see some videos JRB. I have been working on sierra 77gr tmks in my .223 with bad sd and accuracy. Gonna give it one more go with varget then try some 8208 and see if it has a better affect. Sd in the 50s is unacceptable

[@PC-vq5ud]

try some 69 grain MK.

[@donaldweber7636]

I don't see the point of small primers in large rifle cartridges, other than to make problems.

[@ironbomb6753]

That comparator "adaptor" you use to measure shoulder set back, where can I get one? Does it have an angle to match your brass? Sorry for the rookie questions, but this stuff is great...👍

[@JohnnysReloadingBench]

It's the Hornady Headspace Gauge Kit. amzn.to/2RXFTTU Comes with the body and five inserts that cover most cartridges. It is not angled...just a certain diameter hole. For 308, the hole is .400" and measures to that point on the shoulder. If you go check out the SAAMI drawing for .308, you'll see that's the spec of the headspace datum line for that cartridge. Most of the common cartridges are one of the five sizes included in the kit: .330"/.350"/.375"/.400"/.420"

[@ironbomb6753]

Don’t be afraid to go to 43 grains of 8208. My pet load for 308 is a 168 smk at 2.820” with 43 grains of 8208. That load shoots great out of everything I’ve tried it in, including ar-10, M1A, and several bolt guns. Velocity is 2580 @ 16”, 2700@22”, 2750@26”.

[@Jet2416-Reloading]

@Johnny' Reloading Bench - Hey Johnny, I really like what you do. Lots of "Good Stuff"! I'd like to see you do a little something different with the 6.5 Grendel. You've already done the 107gr Sierra. I'm asking if you might try the 100gr Sierra Varminter JHP with an older powder? I'm thinking maybe IMR 3031 or something similar that has been around for a long time and is pretty cheap to use a lot. I'd like to see if it's possible to come up with a load that can reach the neighborhood of 2650 ft/sec without a huge compressed load and a 100gr bullet. (H322 might be a good one but I don't know, I don't have much experience with reloading).

[@sherrypulec1449]

when are you going to do the 129SST bullets in 6.5CM that you kept saying would be next ever since you bought the TC? If you need a challenge get a gas operated 243WIN, powder fill for a bolt gun is somewhat hard to do, but slow burn powders can unlock the bolt to soon on a gas operated rifle, and can damage a rifle. Be interesting to see what powder does best!

[@cam13f]

Hey Johnny, I’m a big fan of your videos. I know you have been having problems with your .308 rounds, I did as well I’m the beginning but I figured out a secret weapon for the .308. Can PLEASE try a video using IMR 3031 as your powder. This powder works absolutely amazing for all rounds I have put through my heavy barrel .308. Anything from 155, 168, and 175 gr SMK, I can get absolutely devastating groups at 100 yds. P.S. The 155 match are absolutely devastating on prairie dogs!

[@Shamaloma4321]

you should do this powder in creedmoor.

[@jimhans1]

8208XBR is a great powder for sure generally, but velocity will be low in 6.5CM though, it’s too fast a powder for heavy bullets (130+) in 6.5CM, but accuracy is good with it.

[@robertvarner7392]

I have seen a LOT of your load development videos with the use of Starline Brass. I have not seen a comparison yet of the difference in accuracy you would get between Starline Brass and the ubiquitous Range Brass brands. When purchasing from Starline, the fact that you only have to tumble to remove oils is minimal brass-prep, in anyone's mind. Is there a definate benefit in accuracy with Starline? That would be a worthwhile test.

[@upnorthbeats6449]

This bullet is interesting, I'd like to see some gel testing with it.

[@ianmcmahon8589]

Jaime Willard I have no advice on the scale, but you can definitely convert a battery only scale to use an AC adapter. That said, there should be no noticeable difference in the same scale between using batteries and an ac adapter. They are basically using a Wheatstone bridge to measure subtle changes in voltage due to resistance changes across a strain gauge.
