That's called "Garand Thumb." Don't let a digit get in the chamber, when you let the bolt fly - like it's designed to do. This thing is designed to chamber a new round - or the next round - under full pressure. Not reduced pressure. Not "halfway back" on the charging handle, and easing it in. Let it rip, like it's supposed to do. Don't baby it - it was never designed for that. "Garand Thumb" below. Don't stick your digits where they don't belong, in the cyclic process of the weapons platform, or you'll get bit. This vid is Slo-Mo - but it happens so fast that you didn't know what happened - until you fucked yourself up. Keep your fingers out of the chamber... Here's some real-time, to make it real.

I'll see if he'll take LC brass, brother. I'll pitch him that my Mk11 load with the Hornady 178 ELD-Ms will ONLY be loaded in LC brass. Forever. I got your back.

This is worth the 21 minutes... WOMEN CAN MAKE ANYTHING AN INSULT!...

Sounds like you're riding the charging handle. Never do this, on a .308AR. Ever. If you're pulling the charging handle back, you let that thing run from full-whack, yank it back until it slips out of your hand and let it ride. If you're loading from an empty mag, bolt locked back, hit the mag release and let it fly. You're riding the charging handle, playing with dummy rounds. You need to go shoot the gun, and let it cycle like it's supposed to cycle. You're inventing a test-criteria - "because you have no powder mass" - you're inventing a test criteria that doesn't exist. Shoot the gun. THIS IS NORMAL... You need to properly lube your weapon, too. I color-coded your statements, and my responses to each statement, to coincide. Hope that makes sense.

He's one hell of an accomplished distance shooter, and what he says makes perfect sense. Find your lands - then get out of them 0.020" or 0.030" - and never look at lands again... (like @Magwa did). But, there's a pattern to follow, which means there's a science. His science is throat erosion - which is land erosion. Get out of the lands, find that sweet spot (seating depth node) in 0.003" increments, and never worry about the lands again. When your accuracy drops off - it's because of throat/land erosion. Sorun it out another 0.003" and 0.006", and see what shoots better in those two - one of them will. You just found your new seating depth, as you wear out your barrel. All this obviously comes after finding the perfect load through powder-level evaluations. I load all precision loads to 0.2 grains for testing, to find the best grouping load. The only load I've ever busted that rule for (my own rule, that I put on myself) is 5.56 precision loads, with LC brass and 75gr Hornady HPBT projectiles, for use in the Mk12 guns - I further refined those to 0.1 grain ladders, for final testing - find the best, at 0.2gr increments. Then, take that load and go 0.1gr on either side. On those, I'm loading at mag-length, and don't really have a choice in seating depth - unless I start going shorter. The load is high enough that going shorter on seating depth is only going to increase my chamber pressure.

Matt can almost field his own baseball team now...

I found an almost limit-less supply of Hornady Match 6 ARC brass brother - for a trade. I have to trade Hornady .308 Win Match brass for it. If you can find some Hornady .308 Match brass once-fired that you can trade out, I'll cut you in on the deal. I'm gonna start with him at a 1:2 ratio - I'll give you one piece of the .308 brass for 2 x 6 ARCs... If he doesn't fall for that, I'll go 2:3 ratio. You get 2 .308 pieces for 3 pieces of 6 ARC. That's my final offer... If he plays hardball, I'll go 3:4 ratio, and give him 3 pieces of .308 for 4 pieces of ARC brass... But that's extreme measures...

Don't load off the lands, brother - don't base it on that... Don't waste your time doing that. Watch this vid, and it breaks it all out, like nothing I've ever heard before. Erik Cortina breaks it down very well. You find a node, then, with seating depth, you'll usually find another node in combinations of 0.003" increments. H4350 is an outstanding .260 Rem powder, so that powder working great here, seems right on the money. I'll find my article that I can link that shows that moving from H4350 to RL-17 made exact same performances, but with a 100fps greater speed. I'll dig that article out. I think it was Chuck Hawks. FWIW, my magic .260 Rem load for the 147s uses RL-22 powder... slower than H4350 and RL-17. But, it's fucking magic...

I yanked that scope out of GunPusher John for 425 green doll-hairs, plus tax, brother. I didn't pay MSRP for it, nowhere close. Common street price that I've found is $499, haven't seen anything lower. I think John has a crush on me. If I move to Skull Valley, I'll probably have to break up with him, and he won't take it well... This scope is badass, and perfect for this gun. Locking turrets, setable Zero-Stop, glass is very, very clear all the way out to the edges, the reticle is FUCKIN' PERFECT for this gun, exposed marked turrets in 1/10th MIL clicks, super sharp clicks, illumination is low enough on 1 that it's easily usuable at night... I can't say enough about it, honestly. I'm sure I'll have more to say after it's been shot - but it's already been out in the yard at night, for initial zero with the laser, and running it through it's adjustments. It's a keeper. I didn't know if the scope length would work out - 11.8" long, so it's a Footer... but it's perfect on there, now that it's mounted. Short, for it's magnification range, but still a damn foot long. It's 25.4oz, so a pound and a half - acceptable for it's magnification range. The Athlon 30mm 20MOA mount is pretty damn nice, actually. That 20 MOA is a huge bonus, gives me 23 MILS of up-travel in the elevation turret, and the mount is very well made. I don't think the LaRue LT-158 with it's 10 MOA - will go on there, once it comes in. There's a HUGE IF in there, because of a plan I have for that mount. We'll discuss that later... I think, with the Athlon mount, I added 2lbs to the gun - but it's a short gun, and lighter than normal, and a shorter barrel with quick swing-weight - so it's easy to handle. I'll get a weight on it sometime, and get that info in here. I need to get this thing out and shoot it, and get the MagnetoSpeed on it with my handloads (and see if this thing even likes them, in the first place). I won't get to gather any data on it until the Shoot next weekend. Once I get the data, and actually shoot it out to 1k, then I'll know more on whether I'm putting that LT-158 on it when it gets here. That 158 is coming in with another part, and that other part is the perfect plan for this gun... I'm just sayin'...

^^^ That's a great, accurate load for Grendels, right there. That projectile performs very, very well.

Let's sort out that gas port diameter problem, and stick a quarter into the receiver extension - and see what happens with the gun - before getting into addressing that lightweight BCG. I have an idea of how to handle that BCG-weight issue - 2 ideas, actually. Let's just make the gun run first, though. It's gonna cost you a drill bit that's about 0.095" (an Irwin drill bit from any Ace Hardware), and it'll cost you a quarter...

7 5/8" internal depth is the number to look for. That's what you'll need to run a 3.250" long AR15 carbine buffer on a .308AR platform. You've maxed out your BCG weight, with that KAK buffer. Stainless body, 2.500" long, and it only hold two weights- and it's already got 2 tungsten weights in it, just to get it to that 5.3oz. That Aero M5 carbine buffer you have is an aluminum body, 2 tungsten weights, and it weighs 3.8oz. The stainless body on the KAK is what gets it weight up to "normal." Your recoil system is solid. Perfect, for what we suggest when you run the 7.000" internal depth AR15 Carbine Receiver Extension. Spring - perfect. Your gas tube length is perfect. Your gas port diameter is a problem... 1.95mm = 0.076771653543. That gas port diameter is 0.076" That's WAY too small. 18" Rifle Gas needs a gas port diameter that's 0.095". I think I've given the range here in the past at 0.093"~0.096". That gas port diameter HAS to go up. It needs drilled. No other way around that. Next - if you keep that receiver extension, the real spec is 6 15/16" internal depth. A long time ago, commercial AR15 manufacturers just started making it 7.000" internal depth - and that works, and it kinda "stuck" as the "spec." However, if you're really at 7 1/16" internal depth - that's too much. There's a quick way to fix this, and that's stick a quarter in the receiver extension, and THEN install the spring and buffer right in top of it. Quarters are 0.069" think, and will take up that extra 1/16" that you've got going on there. You do NOT want to risk smashing that BCG into the ears of that lower receiver, when you do get this gun running... My $0.02 on what I saw. See what a difference "the details" make?

This is gonna drive you nuts, brother - but the results will leave you

We're working on something WAY BETTER than that right now, brother. I'll just leave that right there. Rob will tel you the same thing, too.

^^^ It's unreal what they come up with every year - and every year is a shocker.

Judging that the last post on is was almost 10 years ago - we haven't heard anything like this since. You're on Virgin Ground, if you attempt this. Make sure you report back, so we have some closure.

For that NEXT giant-ass hog that tries to anchor you... I'm sure...

Welcome aboard. This is your issue, right here, pointed out above. Love to see some more specs on your gun, to figure this all out. Here's a great starter on the kind of information that we need -to figure this out over the internet...

I'm glad that you quoted a vendor, that sells parts, and that you ignore years of personal experience on this weapons platform. Ya done good, here, ignoring solid advice. But, you do you.

Ammo is hard as hell to find, but if you can locate some Hornady Match 123gr ELD-M loaded rounds - those are MOST EXCELLENT. I beat that load on my handloads, but it wasn't easy, or fast, coming up with it. It took quite awhile. That Match box from Hornady delivers. It's what everything else should be measured against, for a Grendel.

OH, BROTHER - THIS BITCH IS BAD!!! Damn, this is a nice scope, and it's gonna be perfect for this rifle/pistol... I got the Athlon mount today - placeholder for the LaRue that 4~6 weeks out. It's a 30mm 20 MOA mount - that I might not take off this gun. 30-ish yard laser zero so far, and corrected turrets, and I've still got 23 FULL MILS of up-travel in this one afterwards... That LaRue mount might find another home - if only I had another gun that could use one. My normal scope position is usually "mount the eyepiece at the back of the upper receiver" but this one is different, because it's short as fuk. I've got that scope about 1/2" forward from what I normally do - and it is ON. It's weird-as-hell to think that this 12.5" gun might be my new 1,000-yard gun. We're gonna see - real soon - how all this shakes out. This thing is badass. Leveled this scope 2 hours ago, and this gun is ready to go...

Call 'em on the telephone. I know that sounds weird, in today's world - but call Faxon and talk to a human, for this question.

Hey, you drive on - do your own thing. If you already had it figured out - then why are you here asking questions?... Let us all know how it works out. I'll be thrilled with the after-action report. Best of luck to you. I'm deeply sorry that you were OBVIOUSLY offended by the word "fool", and I hope that the rest of life is easier on you, so as not to offend you, throughout your life. That has to be hard - being offended by everyone, all the time. So, in short, toughen the fuk up, don't be so easily offended, and realize that life is tough. Otherwise, if THAT offended you, then just fuk yourself. Pick what kind of person you want to be in this world that we live in. You have all kinds of options. If you pick to be "easily offended", then life won't be good to you until ALL the Easily-Offended take over. Then you can all attack all the businesses you want with your weak-ass Yelp-Reviews, and extinguish everything that you hate - online, faceless, and with zero balls to live in this world. That's my $0.02 on it. Hope it didn't offend you. Again.

THE Original Intergalactic STUD... Fucked them All, he did... All them bitches...

That one's on you, brother...
