Burning off the grill made an impact on the thermo, that's for damn certain!... I'm cooking now, veggies on and wrapped in alot of tin foil. Here's what burning off the grill at 700+ did... Looks like 114 at my house...

Ironic. Getting ready to fire up the grill, and it's too hot to do that shiit out in the sun. I pulled it under the patio cover. Let's see what the grill does to the thermostat...

Try out the PA red dot, man - you can't go wrong at $129 MSRP, and if you don't like it, I will buy it from you at your cost. No loss on your side, whatsoever. I can't tell you if - or not - it will stand up to the long term punishment that my issued Comp M2 would, but I can tell you that PA products really take some punishment. I know my issued Comp M2 lived through many, many aircraft jumps, with shiity landings like a sack of potatoes, and still kept working - worked in Alaska during a Jan-Mar cold weather rotation, and it swam really well. Lived though an Afghani-Land rotation in some COLD weather at altitudes up to 10,000 feet in the mountains. Same Aimpoint the whole time. I can't say if the PA would live through that, or not, and I'm not doing that shiit again just to test one. However, my only real testament to their quality is this - their mini red dot is tough, as are all their products. I've been running that mini red dot (Aimpoint T1 clone, in it's original model), on alot of different rifles for alot of years. Not one has failed. Not one. The real deal is the one I specifically bought to see how long it would take to kill it - on the 45-70 gun. I no kidding only bought that thing to see how long it would last, and document the round count it took to make it's death. I quit counting the rounds. It's been on there as long as I've had the 45-70, and it just won't die. I think that thing has lived for 3 or 4 years now, under heavy recoil...

That 1:7" twist first came in the M16A2, to better handle the tracers, which are weirdass bullets to begin with. Later, it was automatically adopted into the original M4A1 with the 14.5" gov profile barrel. Colt knew what the hell it was doing. Back to M16 stuff - However, at the time, all we had was the 62gr M855 projectile, which ran better in the 1:7" twist than it did in the M16A1 1:9" twist. 55gr M193 was still around, but the big push was to switch all units over to the M855, whether they had the M16A1 or the M16A2. I got into quite the pissing match with a cadre-base in an NCO training school over this - as they didn't understand the concepts behind it all. Went to a school, and the WHOLE cadre were talking shiit about weapons qual, which was a grad criteria. They were all talking poop about how "You might think you can qual at a certain level at your HOME unit, but WE conduct the qual REAL here - you WILL qual LOWER than you do at your home unit - because WE do it REAL HERE!" Alright, motherfuckers, it's on now... They asked us before the range what we usually qual at home station... easy answer for me - "Scaled paper targets or pop-up range, doesn't matter, I shoot 40/40 and Expert, every single time." They laughed - "You won't do that HERE, not at our REAL RANGE with REAL STANDARDS!" Cool, we'll see - you dickheads will eat your words... So, we run the qual range. M16A1 rifles (training house, with old shiit), and all they can get is M16A2 ammo those days, which was the M855 62gr green tip. That M16A1 barrel, with the 1:9" twist wasn't gonna stabilize those 62gr fatties as well as it would have run some 55gr M193, but it's not a bad rifle with that ammo, at distance - IF you know your holds at 250 and 300 yards for it. And I did... Shot a 40/40 on a pop-up range... They almost shiit, and started making excuses. "Well, you got lucky," and "once in awhile someone comes through here and doesn't do bad..." Eat a dick, you idiots. By course design, later in the course of instruction, we had to give a student-led presentation. My topic was on barrel twist rates vs. projectile weights, and how that affects accuracy at distance... They didn't know what the fuk I was talking about...

I had my choice in the .mil world - Aimpoint or EOTech. I always went with the Aimpoint, which was the Comp M2 at the time. Mounted it as far forward as I could, and ran a PVS-14 behind it as soon as the sun went down. Weird how things work, I prefer the EOTech these days. If Aimpoint would release the 2MOA Comp M2 again, I'd buy one in a heartbeat, though.

That's the truth, in a big way - the general public (General Population - Gen Pop in prison terms ) doesn't even realize that most military people are NOT gun people. I was a gun guy, and militarily, the people I worked with didn't or couldn't understand it. Once training was conducted, and shiit explained, they got it - kind of. Glad you joined, thanks for your service, and welcome aboard.

You have done an outstanding job on that rifle, Preacher!

I don't know if the 77gr projectiles would do "well" in that barrel, but they might. Typically, I'd give the recommendation to not shoot that combo, because you should need a 1:7" or 1:8" twist to properly stabilize the 75s and 77s. I put quotes around "well" above - your rifle will shoot them, for certain - you typically wouldn't get the accuracy out of them with a 10-twist that you would with 7 or 8... However... I've got this sneaky feeling that YOUR rifle would shoot 75s and 77s with great accuracy, and here's where that feeling comes from. First, it's an Olympic Arms barrel, which are notoriously accurate (really, not making a joke - people that dog Oly obviously have never shot one of their barrels). Second, it's not just the "regular" Oly barrel, it's the Ultra Match barrel, and those things are RIDICULOUSLY ACCURATE. Third, you're working with 24" of barrel... I think that thing would do pretty damn great with some 75s and 77s. I really do. Just a feeling, and that would go against normal recommendations for ammo-for-twist combinations. Now I kinda want to see it. If you want, I'll ship you out a T&E care package of Hornady 75gr HPBTs and Sierra 77gr OTMs for loading... I've gotten a very, very slight accuracy edge with the Hornady 75s over the 77 SMKs, so I primarily only load the Hornadys anymore...

Age doesn't matter - if you're keeping yourself Dead Sexy...

Collapsible stock or fixed stock? I know I warned you about Armalite AR-10 parts a few posts ago, but the AR-10 Carbine recoil system is damn reliable, and will work on your build. IF you're doing a collapsible stock setup. Armalite AR-10 Carbine receiver extension (longer than the AR-15 receiver extension, which is commonly used in 308 builds). Armalite EA1095 buffer spring. Armalite AR-10 Carbine buffer, which is really just any old AR-15 H3 Carbine buffer. Add collapsible mil-spec sized stock of choice.

The re-release of the original Primary Arms red dot - it's a direct clone of the Aimpoint Comp M2. They just updated it and released it again. http://www.primaryarms.com/pa30mmrd-ad It's in an Aimpoint QRP mount, but I'll end up mounting it in the Aero Precision 30mm red dot mount.

Damn. Flounder gone. I laughed my a$s off at that guy... RIP, my good man.

Moving forward - making some progress...

Doesn't matter, brother. It's either 16" or it's not. Doesn't matter how far you go over, in this subject.

Armalite AR-10 barrel, 13.5" OAL, midlength gas system, gas port diameter 0.081".

Yep.

Ramshot Tac is a very good powder for loading heavy 5.56 cartridges. I used to use it for the 75 and 77gr loads, then switched to Varget (then, couldn't find it for a few years), and ultimately switched to RL-15. I wouldn't hesitate to pick up more Tac for the 5.56 heavies, at all - I just don't look for it when I'm picking up powder. Tac gets the 77gr SMKs to 2750fps with ease. Here's a bookmark I keep for Tac and 77s... https://www.thehighroad.org/index.php?threads/mk-262-black-hills-blue-box-77-grain.674792/

We've been saying this for years now...

HAAAAAAAAAAAAAAAAAAAAAAAAHAHAHAHAHAAAAAAA!!!!!!

You know... You got yours coming to ya, too...

This happens to me 17 or 30 times a day...

Measured the gas port - 13.5" barrel, midlength-ish gas system, using a port size of 0.081". We'll see how she runs.

H3 weights on a 308 AR run the gun fine, don't have excessive recoil, and don't beat up the gun's internals or parts. You should find that the 308 rifle buffer weighs the same (or very close) to the H3. Gas port size in the barrel is going to have more to do with this than the buffer weight. If you can get a chance, measure the gas port size and let us know. 16" barrel with rifle gas should have a gas port size right around 0.100".

This thread is starting to deliver...

I'm liking the H335 results, brother!!! With 3lbs of it on hand, I'm going to have to load some of this up. I've got about 200 or 225 of the 90 GameKings left, that I was going to load with the RL-7. I need to rezero the new scope, and check that thing out to 400 yards. I might will brave it this weekend, and get my a$s out there early, before the heat comes... Can't wait to see the targets,specifically the H335 groups, even if not ideal. Willgive me a frame of reference on the increasing charge weights. I like the speed you're getting from them. I need to keep my speeds up, for this thing to have the punch I want at 400. I want it to make some exploding coyotes for me...
