For semi-autos, I load to magazine length, or damn near it, and tailor the best load via powder charge. For bolt guns, here's a great video detailing loaded-length: Here's a great section,right here on this board, for you to read: https://forum.308ar.com/forum/34-reloading/

For 150gr loads for .308 Winchester, I only use that for plinking ammo, and I only load Hornady 150gr FMJ-BT projectiles. They have a cannelure, so I seat them to the cannulure-at-the-case-mouth, and crimp them. I crimp everything I shoot with a Lee Factory Crimp Die - no matter what caliber I shoot, no matter if it's for a bolt gun or semi-auto.

Since I trashed your buffer choice so bad, I figure I better explain a little. The buffer design is brilliant. Sprinco actually unveiled that design at SHOT SHOW 2 years ago. Then other companies jumped on the bandwagon, and pushed them to market. Odin's choice of labeling and naming that product is sheer stupidity on their part. But the design is smart. I do have one of those. The AR15 Heavy version. That one buffer lets me test out all my small-frame AR builds (minus the ones that I run with VLTOR A5 recoil systems), and it lets me test out all my large-frame AR builds - because I run carbine receiver extensions that are 7 5/8" internal depth. Armalite AR-10 Carbine receiver extensions, or VLTOR A5 receiver extensions, or MagPul SR-25/M110 Carbine receiver extensions. Carbine receiver extensions that are 7 5/8" internal depth allow you to run carbine buffers that are 3.250" long - AR15 carbine buffers. Run them at the H3 weight (5.4oz), and you won't ever have any issues, on a .308 Winchester shooting .308AR build. Back that up with an Armalite EA1095 recoil spring, and it's a solid system. You might find other problems with your gun, but you won't find any problems with your recoil system. Proof Of Life, I do have one, and I like it.

The Battle Arms bolt catches are very nice, and I use them in everything I build - IF I can find them in stock when I'm building a gun. I haven't used the .308 version yet, but if theey state that it's compatible with Aero M5 sets (and they directly stated that), then I'll be picking up several of them, and putting them in my large-frame guns. They do it right, have no fear, or doubt the product. Your recoil system is gonna be a nightmare. Stating that up front. Don't even consider the spring that you listed. You state Aero M5 for the receiver extension - that's your choice, and it certainly wouldn't be on my list, due to the length. You're restricted to 2.500" long buffers, and specific springs, to make that work in a large-frame AR. Next, that buffer. Now, I'm not hating on Odin and their adjustable buffer - not at all. I'm hating on that short little 2.500" buffer that they LABEL as an "AR-10" buffer. That's complete bullshiit, and why this industry is such a total fucking mess. AR-10 Carbine buffers are 3.250" long - IF they are real AR-10 Carbine buffers. But no, Odin is pushing their product as an "AR-10" buffer, and it's a damn DPMS LR-308 carbine buffer, at 2.500" long. Wrong terminology, Odin - you guys fucked that one up, royally. If someone with a real no-shiit AR-10 Carbine buys that thing, it's gonna tear their gun up on the first round - beat the living shiit out of the lower receiver and the BCG. Dumbass move Odin. Now, their adjustable buffer is brilliant. How they marketed that short .308AR 2.500" buffer is idiotic. If you choose to go this route for your recoil system, and use that Aero receiver extension, be advised that more than one Aero M5 Carbine receiver extension has been made too long, internally. You want 7.000" internal depth. I personally have an Aero M5 Carbine receiver extension that measures 7.100" internal depth - and others here have reported that, too - and it took me a damn long time to figure out why my gun was running like shiit. Get something else for a Carbine receiver extension. If you insist on sticking with AR15 parts for a .308AR recoil system, and run 7.000" internal extensions, and 2.500" buffers, then run the Sprinco Orange recoil spring. Next, the gas tube. Don't buy a gas tube until you can get that Wilson Combat barrel IN YOUR HANDS and measure what you'll need for a gas tube. I have two WC barrels - and needed longer gas tubes, once I got the barrels in, and measured them. AR15 parts usually don't work well with Wilson Combat barrels, unless you're building a small-frame AR.

If you're than hung up on the Armalite barrel that you have, just buy a complete Armalite AR-10 BCG, and run it (the combo) in your DPMS-based receivers.

Nobody has ever been dumb enough to try it, so there isn't any "evidence" that you're going to find online. If someone did try it - we've never heard from them again. Have you found the thread that we have HERE on the measurements, and the differences between the two? I'll link it in here if you haven't seen it yet.

Preachin' to the wrong guy about engine mods, too.

That may not be a bad way to go - and that's another ARC, brother!

HELL YEAH!!! The 6 ARCs are gonna thick as thieves come the Fall!!!

Completely different recoil systems, is why. i took several things away from that paragraph that you stated - but I have to go back to the point that you don't even understand the differences in the recoil systems, or why there are difference recoil systems in the first place... Which is why I posted what I did.

The very title of your thread is "Armalite Barrel..." ...and then you say you have a Faxon barrel. Your Faxon barrel is NOT an Armalite AR-10-based or patterned barrel.

Read this:

Neither is dropping $145k on another truck. I get it, it's a badass truck, but... Come on, Lotto!...

LOOK at those things!!!

Damn, brother... You have NICE HANDS... I'm not kidding, those things are sweet! No-Homo, here. Just admiring your hands...

Check LBE Unlimited. They make the correct gas tubes, also. White Oak Armament will make you any gas tube that you want, when you give them the specs. EDIT - Did you look at the Armalite website, and see that they're on backorder, or did you call Armalite on the phone, and find out that they're on backorder? Calling them on the phone makes a difference. For real.

That's why some solar systems (from certain companies) are inefficient, here in AZ. Because IT GETS FUCKIN HOT!!!... And those solar systems designers didn't know that. Some systems are great, some just completely suck ass.

This is also why I encourage everybody I know to carry - conceal it or not, I don't care - but also have a rifle in your vehicle, that you can get to. Your pistol is only a means that you have on your body to defend yourself - so you can get to your PRIMARY means of defense - and that's a rifle. Pack a rifle, carry a rifle IN your rig. Always be near a rifle, or only far enough away - that you have enough pistol ammo to get back to it, when the shiit hits.

I'd reload that brass, and wouldn't even sweat it a minute.

Exactly. They're trying to put the band-aid on the wrong cut, if they're really worried about "stopping needless deaths." Same as always, though - disarm the population, and tell whatever wreckless story that they can spin, to do it.

Retired from the Army in 2007, and didn't cut my hair for 3 years. Shiit was way longer than shoulder-length, all one-length long as fuk. There's a "Serial Killer" picture of me floating around here somewhere. @DNP remembers my "hair-phase..." Didn't have to get a haircut every week, like I did for 2 decades? LET THAT SHIIT OUT, MAN!!! When it turned into a pain in the ass to put a helmet on, I knew that I'd gone too far. Chopped it. Saved the long-ass ponytail, though, and Locks Of Love will never get that bastard... Won't ever do that gayass Man-Bun thing, though. Never. That's for the choad-smokers.

***Words of TRUTH, right there. I'd recommend it to everyone here, numerous times over.

I sat on this story for 2 days, deciding when and how to launch it. It came through my SOFREP notifications several days ago. This pic, last night, had me realizing that I just needed to post it up, and let it ride.

I didn't forget about Larry - he lived through it and made it out the other side, in one piece still. He was at the top of my mind, making this post, but I wanted to make sure I got the word out to the ones that are in the fight, right now, suffering through this bullshiit that has become "disrespect LEOs". I'm pretty positive that if somebody ever disrespected Larry, during an encounter - they'da been BOPPED RIGHT ON TOP OF THE HEAD, and sleeping on concrete immediately...
