And just like that my day is made. Thanks Johnny!

I'd just like to say thank you. Watching your video's has taught me way more than I ever could imagine. I understand developing a load, how different equipment works, optional items that can make the task simpler, and so on. And it all due to you bud. Thank you so much. I am a better and safer reloader because of your efforts. Good luck this season!

What the hell. I dont have to wait tell Sunday?? Hell yess.... you spoiled us back in the day with dailys then disappeared and now starting to come back regular.. Thank you sir..

Hell yeah two videos in one week

I’m a new sub. I can’t thank you enough for the wealth of knowledge you’ve put on you tube. By far the best reloader video series on KZfaq. Just the business and none of the fluff You rock sir never change!

My sons Ruger predator loves the 168 ttsx with 44 grains of varget loaded at 2.750. It shoots consistently under 1”.

I did some testing with AR Comp, 165 gr GMX and 165gr TTSX bullets in my 308 Sig Cross. The rifle did not like the AR Comp so I tried the same in my POF Revolution and still no joy. I then tried 44grs of Varget with both those monolithic bullets with some great results and was under 1/2" in the Sig. I took a nice 200lb buck with the TTSX and had a nice pass through. Keep up the awesome work!

How did I get here? Is this the 24th? No? Guess I should come back on Sunday. Looking forward to this!

I got home and got to watch two back to back JRB videos!!! I think I’m in heaven. I miss the way you use to say ( man ) Johnny, it was your trademark catchphrase.

Christmas came early this year 2 JRB videos in 4 days!!!! I love the Barnes TTSX and LRX bullets. The 100gr TTSX in 6.5 Grendel, the 120gr TTSX in 6.5 Creedmoor with shorter barrels and the 127gr LRX in Creedmoors with more traditional barrel lengths. I've never got the Hornady GMX bullets to shoot good and I've tried several time in multiple calibers... Great video as always keepem coming brother!!!

Thanks Johnny. I have heard that those monolithic bullets hate a copper fouled barrel. The GMX are apparently the most tolerant out of all of them but if you feel like there is unfinished business with this load, that would be a good theory to examine. Thanks again, love your work 👍👍

Glad to be seeing the 308 again. I'm building one on a 80 percent lower. Same aero upper

nice man ! thanks.

I allways learn something from your videos good work

Love the hunting aspect of your vids, as some of us only reload to get the best out of our hunting loads. Load development is the only target shooting I do. Perfect real world scenario for finding best load for a particular game animal. And that level of accuracy is perfect for the game animal you are after. Thanks for the entertainment and knowledge

I just started reloading .223 a little less than a year ago. Enjoying it a lot. Looking to expand to 308 and find your videos very informative. Thanks

Yay! Twice as nice this week.

Hope you get a big one! Love the 308-AR10 content!

I found the GMX seat tight around the bands on my 270 Win. As well. I can’t get much better groups than you did. Excited to see how they perform on game. Good luck!

i really love the details of your videos and shooting.

Loving the regular videos man

My favorite reloading channel.

Kudos to you sir. Best channel on YT! Good luck with the deer season.

Thanks for the Hornady die test. I have the same die set for .308 and it always is difficult to resize my cases. I was always trying to figure out what I was doing wrong. Thanks for the info.

Because of you, I have started my reloading journey, I have my press and probably 80% of everything I need. I want to thank you for all of your help and knowledge. You are amazing. On a separate note, if at all possible as a beginner, I would like to ask if you can do a video on what powders are a good idea (I am shooting .223), and possibly a bobs bullets cannelure vs non cannelure comparison

Good choice that 3rd group, nothing there that would be considered a flyer. Looking forward to seeing some more 6.5 Creedmoor in the future, it was the 6.5 that you were doing a couple of years back that got me watching your channel.

Glad to see you trying to load copper bullets. That was my goal for this year but no 6.5mm hunting bullets are available. Next year, I want to take a big Axis doe with one.

I also am always on the lookout for things that feel weird

ive got a theory on why those gmx dont shoot well from your gun. You stated the barrel is 1:11 twist, perhaps being those bullets are extremely long for their weight, a 1:10 twist would shoot them better: Length of bullet/bearing surface is one of the huge main factors that faster twists are used for heavier (longer) bullets. i always enjoy the content!

Thank you Sir for.308🔥👍

When using all copper bullets I use a heavy chamfer and deburr both inside and outside of the case neck. My .25/06 shot the gmx really well.

Heak yeah man

Thanks I appreciate your videos good job

Totally agree with the 3rd group. I tried my .308 168 Barnes in a few different powders, and am sub moa to 200 with it. The factory Barnes often ran just over .5” for me, I didn’t play with overall length and used their ogive. Just hard times to play around copper as it’s hard to find and not cheap.

This info is helpful . I am shooting my AR-10 with a 16" barrel at 600 yards using a 6X scope. I'm having good results with the 150 grain Hornady SST. I have just seated them to just under max length of the magazine. I will be trying 168 grain Hornady Match next. I bet the 150's will be better.

Wooooo! 6.5CM AR-10 vids. Sweet! Looking forward to those. Would appreciate any testing you can do with the 147 ELD-Ms.

I enjoy your vids, makes me glad I have a good bolt action.

Thankyou Johnny

I’ll never get tired of AR Comp. Good luck on the hunt, I hope the whitetail gods are smiling on you.

I have the Wilson expander mandrel die that has the window. Works great!

I personally opinion on lead free bullets is go light weight bullet theses things love speed the faster the better in my finding!!

I think they're called gas checks. The grooves in the projectile.

It’s like my dad that left years ago to go get cigarettes is finally back!!

I had the same experience with the GMX I was using the 125grain 30cal in my Ar-10 in 308. I was using N-140 powder and I was pushing them close to 960m/s with maximum loads but accuracy was terrible about the size of a plate and bigger, as the velocity dropped down to 850m/s I got quite good accuracy about 1moa or something, I wasnt changing the seating depth a whole lot, i was just using the CIP overalllength. The GMX is wird somehow I thought it might be a flatshooting and deeppenetrating load but with these accuracy problems, I will try the ttsx next. Best regard from Europe, yes we also can have cool things here ;)

Yep, third load. The lower vertical dispersion is the best, and like you said "150 yards is a LONG shot", for where you hunt.

I think the top band is for loading high power 30 cal 308 300win mag 300 weatherby. But I'm pretty sure the bottom band is for 300 blackout lengths. Possible but I dont have the 2 in front me. Loving the chicken vlogs, ur doing well.

I use the Black Hills 262 clone I stole from you to make a good day, shoots great, always!

We need more 6ARC! I just bought a proof 18” 1/7.5 and I can’t wait to see how she shoots 105 bthp

With the all copper bullets, I like to go lighter to get a bit more velocity to insure expansion. Personally, I would use the 150 GMX in the 308. The 168 will do well for your hunting. As you found, the all copper bullets are much longer than their lead core counterparts and take up more case space. I use a 168 Barnes TTSX in the 300 Win. Mag. In the 30/06 the 150's and in my 270, a 110 @3250 FPS. Buddy took a nice Elk with the 168 300 W.M. and a Pronghorn @ 300 yards with the 110 270 load. The all copper bullets are a bit of a different animal.

I do like your videos. I myself live in Kentucky as well. My shots get to about 155 yards out of the primary blind I shoot from. And as you say you really don't need to group that well on those shorter ranges. ARs are fun to shoot but honestly the bolt guns are better for hunting. One thing I thought I would mention is a 1-11 twist for a 308 isn't all that good. Most of them are a 1-10. The copper bullet is much longer, and you really need a higher twist barrel for it to shoot tighter. I would be shooting 150 grain flat based bullets out of that AR. Just saying the twist rate on those longer bullets isn't good.

Both of the tests together are great, though. I like that you can see how the POI has a general trend downward, between the two videos, up until the final string where it goes back up and then to the left a bit. I trust that it is the load that throws consistent fliers. It almost looks like it wants to start to make a group, but then it has one or two outliers that are just fuck-all. If you were to continue testing - some time down the road - to see what the best group you could get with this bullet could be, it would probably only be worth it to do a slight increase or decrease in powder? But for hunting, any of these groups are going to get the job done, though, and be great.

When I loaded 168 sierras for my .308 I used to shoot just under 2700 to get the best groups. And they had to touch the rifling

1 variable at a time. Painful but most effective way to eliminate problems

We all have bad days, thankfully there’s more good than bad!

I abandoned the GMX. I was having pressure signs well before the barnes bullets and they didnt shoot as well. I tested in .270, .308, and .30-378. All the same issue.

Alliant powder has been rare as hen’s teeth the last year or so. Wish i could find some

Johnny, if you decide to work on the short barrel load for the 223 again the offer still stands if you want to borrow my 7.5" upper. I am just over in Central Kentucky so no big deal. FZ

They're a little pricey, but they're in stock at cabelas and midway if you need more bullets

That has pretty much been my experience with my AR10 in .308. It shoots a good group now and again, but man it is picky. And I'm still trying to figure out how to get the brass sized so it won't get stuck in the chamber. When I get really frustrated, I pull out the 6mm Creedmoor, pick a charge, seat some bullets and it shoots great. When I want to get aggravated, I go back to the .308…

Got some of the165gr Hornady GMX on clearance a couple of years back. Really like them for the 308. Have had thoughts of trying them for the 300 Win Mag.

Thank you for a second video this week! So in the end the GMX is ehhh to yuck!

Your the man

Did someone say 308 ? lol. Great video 👍

You keep talking about how you've struggled with lead free bullets but if I remember correctly you had some decent luck out of the barnes tac-tx in 300 blackout a couple years ago.

Hey can we get some more 357/38 videos? I am working with my revolver more and would love to see some videos with the 110 Hornady XTP in these cartridges. Take it easy buddy nice work!

Revisit your 168 sierra mk load and order a couple more mandrels and see where it takes ya. Mandrels are cheap and it would make for an interesting video to see if you very well could shrink your group size/sd/ES. It's a neat rabbit hole to go down. Oh BTW I'm shooting an aero precision ar10 308 lapua brass, 210 primer, 175 sierra match king and imr enduron 4166 powder ar 41.2 grains. It has good speed

I bet that gmx would be a killer long distance hunting round in my 300 win mag. It pushes 165gr interlocks at 3200, which is great for trajectory but messy if a shot is under 150 yards or so. The gmx would hold together alot better at those closer range, higher velocity impacts

Perhaps when seating the bullet you are expanding the case...due to elasticity when the case mouth hits the groove it is snapping back a little then expands at the next band without that elasticity you have no neck tension.

Great video agin jrb. GMX will do the job for sure on a deer but some reason that bullet ar comp don't work well in that gun wonder if different powder would change it. Also you plan on doing any more 357 mag hunting bullet reloading? Or some more 22-250

If you learn something. Even if its a disaster. You haven’t waisted time. Don’t blow your face off:)

Hornady caved. Let's go Brandon!

Sorry about the 2 chickens Alfred.

Great info as always - just 1 Q - when seating bullets do you lube the "freedom seeds" before ?

Is there a reason sierra doesn’t make copper solids? Insanity Johnny!

Good stuff! Hey, were you ever able to bag anything with 6mm ARC? If I remember correctly last deer season was a bust for the ARC.

Hi Jonney I have the same problem with the lead free projectiles. The Tikka T3 11 twist 24inch shoots under half an inch groups all day 165~180 gr range lead core projectiles. But same weight hunting copper projectiles groups are garbage. I think that even though they are the same weight the density is different, because of that the projectile shape which is normaly longer and bigger than the lead core might be effecting the barrel friction and spin ect. It might be worth trying a longer slow barrel like a Palma Match guns or super fast twist barrel 8 or 9. It willl be interesting to see the results.

With the col getting smaller would that effect burn rate with stick powders? Less air space not allowing it to burn as much.

Monos are super finniky IMO. Couldn’t get etips to shoot under 1.5 inches in my tikka for 3 shot groups. Chuck in anything Hornady or accubonds and shoots 0.5-0.75 moa all day

I was kind of hoping you’d break that 1” mark, but close enough. Good luck with the hunt this year!

I’m looking forward to your results on game. I head shot a 372lb Maine black bear in September with this bullet in 30-06 with no expansion.

How do like the RCBS Rebel, thinking about upgrading my old rock chucker.

I still think you're in that no go velocity range for .308 win. 2650 or 2750 is magic. You may sometimes find something in between, but rarely.

LE Wilson makes the neck sizing die with the window.

I'm new to the AR-10 game, I have a Stag Marksman 18" in 308 win. I'm having a hard time getting 1 MOA out of it. I whole heartedly believe that I am the issue. I've gotten to 1.25 in but it is NOT consistent. I have allot of experience with precision bolt gun shooting. Can anyone point me to any information that can help me be a more precise shooter with the gas system rifle. I can't seem to find what will help. Also thank you for all the work you do Johnny, this is priceless information.

Johnny - have you seen the new Hornady CX bullets? They are a copper alloy solid like the GMX with the ballistic tip like the ELD's and others. The bearing surface grooves are different than the GMX and they have a slightly better B.C. I absolutely loathed the GMX bullets because I could not get them to shoot well no matter what I tried. Maybe the CX will do better. Hey, it's Hornady, it's gotta be worth a try.

RE AR Comp, shoot what you got!

What part of Norteast KY? That’s where I grew up. Live in Lexington now.

Good vidja 👍, let us all know where to get 8pounds of comp please 😜!

I don't thing it's wasted Johnny. Just found what doesn't work. "I've Just Found 10,000 Ways That Something Won't Work." Thomas Edison

Johnny, what did you think of the GMX as a hunting bullet? I shot a buck at 86m last year with a 185gr GMX out of a 338 WM (excessive I know). Bullet should have hit going >2850fps and yet I saw no evidence of expansion. It was a broadside shot and dropped him where he stood, but the exit and entrance holes were basically identical. Lots of hydrostatic damage and fragmentation of bone, but the bullet didn't appear to expand. I would have liked to recover the bullet, but it was somewhere under 2ft of snow.

I notice faxon 7.62x39 AR-15 barrel is .308 bore. I notice other makes are .311 and .310. Faxon says, all diameter bullets run in their barrel. Any thoughts?

What's the recommended twist rate for that bullet? Typically monolithic bullets prefer a lil bit faster twist. Not saying they're not stabilizing, but maybe they just don't like that 1-11 twist.

Have you had any problems with full length resized 308 brass trimmed to 2.005 not allowing your bolt to close? I have had this happen with a set lee and rcbs dies and don’t know why.

I wonder if the GMX is a bit long for your twist rate? According to strelok your gyroscopic stability factor is only 1.3 with the GMX at 1:11. The SST is up around 1.9. Might be that the bullets are wandering a bit due to yaw? The 150 GMX might stabilise a bit better?

Would the over worked case have higher pressure,,,,,,, it’s pressed smaller??????

Where are you getting AR-Comp powder?

Should try out the new cx bullet

Are you gonna post a video about the hunt I wish !!!

What are the gauges you use to measure shoulder bump

Were the primers suppose to be 34s instead of 41s?
