Oh, it is, brother. Last year during the High Angle training, @Matt.Cross made it his personal SPECIFIC point that he would shoot every single target from the prone, sitting, kneeling, and standing positions - and he did it and hit every one. That was Commendable.

That is THE LARGEST Appleseed group in the country - more instructors, more students through, largest classes... They are the organization to follow after, as far as sticking to the course curriculum. I'd LOVE to head their history classes - bet they're damn good at it. Congrats! Use an adjustable sling, and it'll allow you to make rapid changes, rapidly... <<< I like verbiage like that - I learned it when I worked in the Department Of Redundancy Department... I highly recommend the V-TAC Mk1 sling, in whatever color you like the most, that they make. Makes sling adjustments very easy. You'll find that once you get your sling set for your length-of-pull, and body - it'll stay there. When the time comes, let me know, and I'll go over what I do with them - I set up an index point that I can always go to, no matter what, and it's perfect for me. Set it there, perfect tension, when I'm slung up tight. I run a hellish long distance shoot over here in AZ twice a year. You should consider coming over. You're new, no one knows you here besides Albro... But we think he's okay... Right @Albroswift?... As an Appleseeder, alone, I'd welcome you into the chaos that becomes every Fall Shoot. Albro is your bonus... Next one up is 5-9 Nov.

You ROCK!... You have no idea how much I advocate this event - "GO SHOOT AN APPLESEED, FUCKERS!!!" - and I do it routinely. Nobody listens. I was an Appleseed Instructor, before life overcame time. I did it for 3 years. People don't get it, or they laugh when I recommend it - it's the best rifle-skills training you can get, for near-free. To the dumbasses that don't listen, or think they're "above" this... Not only will it teach you some SERIOUS Marksmanship skills - it'll teach you a little bit of important information about this country... ALL you fuckers are missing out, if you don't drag your lazy asses out to an Appleseed Shoot near you. That's on you, to figure out the time. They're everywhere... Click this, find one near YOU, and drag your dumb ass to one... You fuckers never listen, though - you're too "good" to do one of these - you're already "above it..." <<<That's a mistake, in your judgment... Hit it: https://appleseedinfo.org/schedulemap/

@308kiwi, thinking about you, brother. Praying that it's going... decent, at least... Miss you here, man...

Go read the thread I linked in here... His chamber is not your chamber, his barrel is not YOUR barrel. Respond again once you've read that thread. Until then, you're just searching, blindly, for information that we can't provide you. Go get a grip on on the mechanics of this gun, recoil systems, gas systems... Go get your head around THAT information. Then come back. If you're gonna be lazy, and not take advantage of the information provided - I have nothing more to say. I'm done with this thread. YOU go put the work in, now. Or, whatever...

If your buddy's brass wasn't fired from your gun, then that doesn't matter what his fired brass did in your gun. Fired brass is expanded brass - that's why you have to resize it, before you reload it. It's not uncommon for fired brass to NOT just slide right into a chamber. Ammo differences, as well - so, your buddy fired his own brass, and then it was going into your chamber - was he firing the exact same ammo, loaded to the exact same pressures, as what you fired? And through the exact same barrel configuration, from the exact same barrel manufacturer? Probably not. You need to try to compare apples to apples, and not compare apples to hammers. Doesn't work. Don't try to invent tests for this stuff. You'll only frustrate yourself, with findings that don't mean anything. Hope that makes sense. Go drag yourself over to that thread link I posted, and get yourself ass-deep in it. It'll help you understand.

With a decent scope with enough internal elevation adjustment, a 10moa mount will be fine for most distances that most people shoot - what's the ultimate distance that you'll wring this out at? LaRue LT-158 is my favorite mount for these. If you really want to stretch it, to it's max capability, depending on the scope you choose, you might need a 20moa mount. Scope internal adjustments, mount cant, and what you'll really do with it - those all go hand-in-hand. 10moa will serve you just fine for most modern, decent scopes, to 1k yards.

You'll get carbon fouling on every single new AR that you build, no matter if it's AR15 or Large Frame. That happens, every time. Until you build up enough carbone fouling to SEAL these parts - you'll have "gas leaks" - and it's no big deal. Shoot the gun, create carbon fouling, seal your gas system. That's part of the game. Every one of them...

1st - I never said you were overgassed. 2nd - Everyone else (online) is incorrect, and probably don't know what they're talking about - not enough time on the system, to even understand it. You have two things going on - you're UNDERgassed and definitely UNDER-RECOILED. You don't have enough buffer weight to control and Ass and Mass of a .308AR standard BCG, and your gas port is too small. You're compounding problems with problems, here. Read the thread I linked above. Ask questions after you've read it.

Yeah, no problem - read this thread here:

You'll be that guy. There's about zero discernible difference between a 147 and a 150, so there's no reason to start out slow. Just run 150 data, straight up. Let us know how it works out - report back on the load. It helps everyone, at one time or another.

This is all good news - this is gonna be a great cartridge. I'll consider making a 12.5" pistol out of one - but there are no barrels like that out there right now. Any idea on the speeds of those ones? Hornady is listing 28.1 grains of Accurate 2520 as their max load for that powder, giving that one 2500fps from an 18" barrel. I'll be taking that one north of their max, I can see that now. Testing, testing, testing. They don't even list a powder that will give me the 2666fps that I got yesterday, and all their load data is 18" load data. I'm thinking I'll rip one of these Match rounds apart and see what's going on inside...

That's PERFECT, right where it is - don't change a thing with it.

That'll work.

Buffer weighs 3.8oz, right? Too light. The spring will suck, too. Proper spring for an AR15 Carbine Receiver Extension (which is what you have) and the 2.500" buffers is the Sprinco Orange Spring. You're borderline on the gas port diameter. 18" Rifle Gas is gonna need a little more than 0.089". You need a 5.4oz buffer, or as close tothat as you can get, and the spring I mentioned. I can give you a $20 option for the buffer situation, that will be way better than what you're running now. Requires a little work. I know you say you lubed it up - but that thing is BONE DRY in that pic you provided, and that's never good for a large-frame AR. They don't need "just a little lube" like an AR15 - they need to be borderline dripping with lube. Heavy lube. First thing you need to try is to lube the hell out of it, and shoot it again.

Nope, not at all - not with the barrel you're using. Doesn't make sense, for that barrel, at all. That's the Fulton Armory profile and specs, that Criterion makes for them. Clint McKee wouldn't let a bad design get out, not with his history. Change the scope - do the easy thing first. That's the Vortex budget scope, that you have on it. Bad ones can and do get out, from every scope manufacturer, once in awhile.

That changes things. ^^^ Because of that, right there. I'll figure it out, and post back in here.

^^^ Yep, what he said.

Damn, brother!!! That's IT!!! Your Google-Fu is STRONG, my man! https://www.firearmsunknown.com/blitzkrieg-lr308-bcg-black-nitride-dual-ejector.html

That's rifle-length gas system with a dwell time like that, on a 22" barrel. It's gonna be an 8.875" dwell on that. What's the gas block diameter - barrel thickness for the gas block?

It could be - quickest way to find out is to swap that scope out with your buddy's scope. If it's still doing it after that - it's the gun, somehow. Something in there is messing with it. Post a pic of the gun, if you would please.

This will work right now for a Drop Chart. I'll verify the 850 next Sunday. This is pretty damn close. My input data is correct, but it was a little hotter out once I went after that 500/482. Keep clicking it -it gets bigger. I think it's 3 clicks, total, and you get the large, readable version. Pretty damned impressive for an 18" gun.

Supposed to be heading into monsoon season - even though it has barely rained here, like zilch. It's a little humid in the mornings, but as soon as the heat comes out, it's gone. By 0925 it was already 101* and 22% humidity.

I can pretty much say this chart is fairly accurate,after seeing my speeds today. 2,666.57 was my average of 7 shots, with a standard deviation of 7.7.

Only thing I had with me was the Grendel mags - I completely forgot to take a PMag with me. I'll hit it again next weekend, because this thing is going over to the 850. With the data I got today, I'll make up a chart tonight for it. I gotta hit that thing at 850 and confirm the chart. Only shot 50 rounds today - enough to load up some ladders and get busy. 2.6 mils at 482 yards - just blew me away, brother. That was nuts...
