Since my last post JUST earned me "Rookie Badge", I think the warning points are more important to me now...

I want my original warning points back...

Go get the gun back from the gunshop - or leave it with them and ask them for your money back. Either way, is the best thing that you can do. They don't know what they're doing. We'll build you a gun, or fix the one that you have (depending on that barrel). The marks on those rounds you posted are from slamming into the feedramps. If it was mine, I'd tell them that it's fucked beyond all repair, and I want my money back - they can sell that thing to someone else.

DO NOT BUY a RRA 2-stage trigger. Long term, you're wasting your money.

Exactly - Compressed load is compressed load. Not all loads are compressed loads, either. Very few. I come close to a few on some of mine, but don't get that "CRUNCH" on them. It doesn't matter in the least on a gas gun, if you crunch it by seating the projectile, or turn it upside down and crunch it in the base, at the primer flash hole. Compressed load is compressed load. If there is space-in-the-case, and you're not loaded to 100% case capacity, then the powder moves IN the case. Doesn't matter if you loaded it normally, or upside down...

That will help, drastically - but not so much in this case. If you have a 7.000" receiver extension now, that means that you have a 2.500" buffer in there. The only way you can GET a 2.500" aluminum-bodied buffer to 3.8oz (H1 weight) is with two tungsten weights. 3 weights won't fit in a 2.500" buffer body. You already have 2 tungstens in there, in the buffer that you have. I have options for you, though.

Since you're "AD Military" in your first post here, I'm sure you know that the statement will get you praises for your service - but, as you probably already know, as AD Military - not many people in the service are "gun people." Many don't even know how their issued gas gun even fucking works. Very few in the .mil world are gun people, unless they've been bitten by the bug after real Sniper training, or Designated Marksman training. Most .mil people have no idea how to read the wind and make corrections. No clue. So, in full disclosure, I spent 21.5 years in, and punched out at that point. I WAS a gun guy, whilst in, and pushed all my people HARD to learn the way the AR worked, why and how it worked, to better understand how to clear it when it fucked up. No matter what the weapons platform was, Mk19, M2, 203s and M-79s, 240s and 249s, the 60 in the old days, whatever.

We've both hit the IPSC plate at that mile, too. You're asking for alot - that's already been posted. All my load data is posted. I've never heard of some of the shiit that you're talking about for making a precision load for a gas gun - upside down case? Nope, first I've heard, and it's not necessary to make accurate ammunition. Neck bushings? That's bolt-gun shiit, right there. For gas guns, you need to be crimping these things, not "adjusting neck tension" with different sized bushings. Crimp, for real. I use IMR 3031 for my 405gr 45-70 loads. Not for my .308 Win loads. Better powders out there for the .308 heavies. Way better powders out there if you get into this .264 / 6.5mm game. I'd use IMR 3031 as a backup powder for my 300 BLK loads and my .30 Carbine loads, though. But it's not my primary powder for either of those.

Truth...

Laughing again, now... I just made that one post ^^^, and now I've earned "Posting Machine" for my 500th post...

I just saw this, and laughed... loudly. I have 3 badges now. one week, one month, one year... I see it goes to Grand Master, so I'm wondering what that is, because right now, I'm not even a "Contributor." This is why I laughed. Loudly.

Fired a legit World War 1 1911 this morning. It was a treat. I was so excited to fire it, that I didn't get any pics of the gun. It'll be around again, and I snatch some pics, and get them in here. What a hell of a pistola.

OH NO YOU DIDN'T!!!

That thing looks nice, brother - there's 30 MOA of HOLD in elevation in that reticle! Worth the risk, all day long.

Definitely leave the 10oz buffer in there, if you're keeping it .308 Win. I've personally seen the benefits of that, myself. Keeps the scope ON target, after firing. For all that other stuff - if I was building a 6.5 creedmoor for distance, I'd be loading the 147 Hornady ELD-M. The 153 A-Tip doesn't give enough benefit in BC over that 147, to switch to it, and it's added expense. Ironically, I'm loading 147 ELD-Ms for my .260 Rem. That's the one... For everything else - what you're describing for precision loading of ammo (I think) - I don't do any of that stuff. Never heard of it, before you mentioned it. Especially turning a round upside down before seating a projo. the only thing that is gonna answer most of your questions -reverts back to one of my earliest questions. Distance. Your gun is already built with a very, very nice 18" barrel. I run an 18.5" very, very nice barrel. It's supersonic to 1050 yards with a 178 expanding hunting projectile. What you need is up to you - not any of us. The one I have does exactly what I need it to do, and then some. Would I change it? Nope, not a single thing. I wanted a gun to do something different, so I built another gun, the .260 Rem.

Lots of good stuff out there, to jump on. BA has 15% off everything, KAK has 15% off everything, SAA has 5.56 nitrided BCGs for $75 ea, limit three.

Projects like this turn me on.... I like where you're going with this one, Albro.

Same here, to all my friends. Where i work, family-owned, they believe in the holidays, so we had today off. went shooting this morning, just to take advantage of that precious time.

That sounds like a solid parts list, full of damn good hardware. You will definitely see a flatter shooting projectile in 6.5C, for sure, and it'll have longer range before going transonic, and carry more energy on impact at those longer distances. My opinion is that the proper .308 win round can be very effective, and do very well at distance - but it's still not going to beat a good 6.5C load, nor .260 Rem load.

Genius, Mike! WET THAT SHIIT DOWN, BROTHER!!! That's a damn good system, right there.

Gas PORT DIAMETER IN THE BARREL, or is that the gas block journal size? The size of the gas block that you have to fit over the barrel?. I'd like for you to link those other posts that you've referened, right here in your thread, below. I'll look at them. So, barrels details are necessary, and it's necessary that they're accurate... 22" Criterion barrel. Got it. Rifle gas system. Got it. What's the gas block journal diameter on the barrel, and what's the gas port diameter IN the barrel? the numbers you threw up there are kinda all over. 0.085"~0.095" covers everything in a 0.750" journal diameter from 18" midlength gas .308 Win all the way up to 18" and 20" rifle gas .308 Win. details are important. If you're on rifle gas, 22" .308 barrel, you're gonna need to be on the small side of some of the numbers that you've posted. Pending journal size, of course. What size was that BA non-adj gasblock that you bought? It's either 0.625", 0.750", 0.875", or 0.936". BA doesn't make two of those sizes, so... that will answer the journal diameter question. Only other question is what size gas port did Criterion put in that 22" rifle-gas barrel?... Don't sweat it - we'll get this gun running. It just takes accurate details to figure out what needs to be done to it, if anything.

Receiver extension is the required 9 11/16" internal, on the money. Buffer should be 5.200" long and weigh 5.4 oz. Recoil spring should be 100% identical to the Armalite AR-10 EA-1095 spring. No other substitutes. Dimensions of that spring can be found on HeavyBuffers.com, in their "reference" link. Gas tube is the right length. What's your gas port diameter in the barrel?

This match is gas-guns, 100%, brother. No bolts allowed. This is PRS, in all reality - but gas-guns only. Nothing else qualifies to even head to the starting line. Questions have come up about M1s and M14s - but none have ever shown up. They'd probably be allowed in. General Rule is - if it ain't an AR, it can't shoot this match.

PSA fails on this routinely. They send PSA PA-10s out the door with AR15 recoil system parts in those guns. Been documented many. many. many times. They just don't care. It's pretty easy to determine if one of the large-frame guns is "overgassed" - the MOST common mis-diagnosis, in all of times... OR if the gun left the factory UNDER=RECOILED. Everyone that tells you that you need an Adjustable Gas Block to even make your standard gun run - is full of bullshiit. Standard guns should run out of the box. If the answer is "adjustable gas block" - then your recoil system isn't up to par. it's far BELOW even what the minimum standard is. But, cheap manufacturing processes make cheap guns that shoot cheap ammo, for most of the people out there that will never know the difference in the first place - and those cheap guns will work for those cheap rounds that most of the people looking for a cheap gun. And when that cheap gun fucks up - they won't care - or maybe they will, and they'll send it back for that "lifetime warranty." The answer they get back is that the gun is fine, worked during testing, no issues. I'm not clairvoyant - already seen that a few times here.
