I just went back and looked at these two pics... Exactly what's happening right there is this - that hot brass hasn't contracted enough yet, in the cycle of operation, and it's stuck to the chamber walls still. That BCG is already beginning it's rearward movement, forcing the cam pin cutout in the BCG to rotate the cam pin - and turn the bolt. While the brass is stuck to the chamber walls. That's what causes ejector swipes. Commonly, it's not enough recoil system. Not the case with your gun setup. Secondarily, it's not a bad gas system that isn't balanced to the proper recoil system. I wouldn't suspect that at all with your BA barrel, and your statement on gas tube length, ending in the center of the cam pin cutout in the upper receiver. Your gas tube length is good. Only other thing in the gas system that can cause problems is the gas port diameter - but I wouldn't suspect that coming from BA, not in the least. Too much gas port, and you're running hot, too much gas. Not on my radar, from BA. That leaves hot ammo. It's the only other thing that's easy to test, without putting tools to your gun to check the gas port diameter. Run 5 rounds each of all those ammo choices that you shot, document the info from each ammo brand (MV AVG, SD, ES), and let's see where this goes, or leads us. If all those ammo speeds check out, we're pulling the gas block screws, sliding it forward, and measuring gas port diameter...

Yeah, benchrest type guns for .223 Rem. I don't think there's a single AR manufacturer left anymore that's still chambering .223 Rem. It's just bolt guns, now. For .308 Win chambering - it's almost everything on the market. Hardly anyone at all chambering 7.62 NATO. For 5.56/.223, the chamber that's taken over that market by far is .223 Wylde. It's a mix of .223 Rem and 5.56 NATO, with a leade dimension that's in between .223 Rem and 5.56 - you can shoot whatever you want through it, and it's more inherently accurate than 5.56.

I am quite familiar with this subject. Leaving it there. Also, research JTF-510, JSOTF-P, and TF-121. Proud to be on-ground in all of them, in them. Bonus... Operation Winter Strike. The ONLY thing that would have made it better - is if it sucked more... RLTW

I've preached this for years - about 15 or 16 of them here. .223 Rem vs. 5.56 NATO. What you see here is the direct opposite for .308 Win and 7.62 NATO. I stand by that. Both statements. They touch on that.

He speaks again - softly, but with massive volumn... https://www.youtube.com/watch?v=CKcIghRFNmA ^^^ Gotta click it. YT doesn't "allow" embedding that link, because YT is fukcing GAY...

I'm with Rex on this one...

You are on the right track, man - and you have the tools to find out the info. FWIW... In the future, I have a MagnetoSpeed that I can send out, when people run into this kind of issue. I'm not saying I'd send it out just all WillyNilly, to any random jackass that shows up on the board... But I would send it out to reputable, trustable, known members of the board.

Why does this not surprise me...

^^^ TRUTH, right there...

Bro. There ARE NO "perfectly good aircraft..."

HELL YEAH!!!

Absolutely. A recoil system that's too light, not up to the task, lets that BCG start unlocking early. That rips rims off brass - brass that hasn't cooled and released from the chamber walls, sticks to the chamber walls. Too large of a gas port, too much pressure going through - that's typically not the issue seen with gas systems - usually, the ports are too small. Could be a few things... Based on the specs you listed for your gun, I'm not going to condemn the parts, or port size. You selected very great parts. Focus on the ammo, with that Magnetospeed...

"At least they're not Legs..." Disclaimer - if you're not Airborne, you won't understand...

That news sucks. Chris is one hell of a great guy. Hate to see this.

That extractor mark on the rim - that's telling of a hot load. It was trying to rip that stuck brass out of the chamber. So, if it's not the ammo causing this - it's the gun not being able to handle the ammunition. Something is making all those loads look like hot loads - and it's not always ammo. Have a chrono you can shoot these thing through? That will give you some immediate answers, right there.

That doesn't mean anything, because of springs. Springs twist when the expand and contract, so they turn things, in motion. Even if you very carefully lined up every round in the magazine, exactly the same, all the wording directly matching in the mag, same angle - the springs will twist 'em. Where the marks are, compared to the words on the headstamp - not an indicator of anything. You have hot loads, plain and simple. Maybe the ammo is hot - maybe the gun configuration isn't handling the pressure of the ammo you're using. Something is causing that to be hot ammo in that specific gun.

Finally coming down around here. No more triple digits for the forseeable future. I'm happy about that, in a big way.

Does the pic of the brass directly follow the ammo listed, in order? Like, left to right? First ammo listed is the first piece of brass on the left, etc. You have a dual ejector bolt, but only one swipe on the brass - and the swipes seen are big enough to catch your fingernail, where you'd have to file them off to reload them. That 3rd piece of brass has no ejector marks on it at all, left to right, 3rd one.

Tell you all now, a big part of the reason we all do what we do now, with the Shoots - is to pass information. They passed it to me, back then. I need to pass it on to someone, so it doesn't get lost. That's why we've been doing these shoots for so many years now. Information, and training, that is NOT passed on - is information lost, and forever forgotten. RLTW

Yeah, brother. I shot a match on Saturday, 3 Oct. Gave a speech beforehand. 33 years since that firefight happened, and it was the most intense firefight since anything that happened in VietNam. 18 dudes lost that day, all badasses, between Delta and Rangers. The two most giving people lost that day were Gary Gordon and Randy Shugart, that requested multiple times to be inserted on the ground to secure the Durant crash site - they knew exactly what they were asking for, the first time they asked, and were denied. After multiple requests to be inserted on the ground, they were approved, they went in. For what they gave, Mike Durant is still here. Ultimately, after many years, both were approved for the CMOH. In the very late '90s and early 2000, I had a bunch of those guys in my unit, sent there to build leadership and progress themselves. The medic? Kurt Schmid, he was a CW3 in my unit. John Macejunas was HHC 1SG. Jody Nacy was the Group CSM. There was a complete pile of them, in 1SFG(A). Everything they were sent there to do, was accomplished, and we went nothing but up. They built capabilities, skills, and mindset. Bad Motherfukcers. A few years later, in Nov-Dec 2003, in Afghani-Land, I directly worked with Jeff Struecker, from that battle in '93. By then, he was a CPT, and a US Army Chaplain. I've never met a more badass Chaplain in my life. After an IED blew up the gun truck with Jay Blessing and Gary Toombs, we went back out there the next day, to the IED site, and held a ceremony, Chaplain Struecker leading. The message was simple. Try again, and see what happens. Jay Blessing died, only casualty of the deployment, Gary Toombs made it - in 1995, he was one of the SF Company Sergeants Major in 2nd Battalion, 1st SFG(A), when I first got there. He'd since retired, and was the Civilian Contract Armorer at 2/75 when that IED blew him up. The lessons learned from Somalia were definitely passed down - directly, from leaders that were there, years later, in our unit. Those men were the reason we had monthly shooting competitions, just for bragging rights, and a name on the trophy that was posted in the Mess Hall - but, to build capabilities and skills, foremost. Those men were the reason that we had a private range built, directly across the road from the front gate of the compound - that we had full control of. Those men made a difference in the future of 1SFG(A), forward, and changed the direction of warfare, post 9/11. At least for us, but I'm sure, completely, for the rest of the units that they were all sent to, besides ours. In my opinion, we got the best ones. Mace was unreal... Nacy - unwavering, and badass as all fuk. Doc Schmid - coolest dude you'd ever meet, so layed back, matter of fact, and so on point. Completely calm, collected, in everything that he did. That was a valley of heroes, and we were blessed with their presence. They had a job to do, go back to White SOF and train people - and they did it. They changed trajectory. For the better. Not long after 9/11 happened, all their training paid off, for us. To them all, in 1993... Rest easy... For those that made it out, and eventually found me, and changed me... I can't thank you all enough...

Why you selling it? Those are new, but they're pretty good scopes.

Worst case scenario - just teach them how to tread water...

I have 200 of the 75 ELD-Ms I can load up and try, just the boolits into cases. The Berger 85.5s did the best for me, before I got all pissed off and took the 22ARCs out of the match/competition rotation. I literally went back to 5.56 guns, Mk12s, for the matches.

I love this... 😍

I made some for a shoot, and it worked. Couldn't get any vid of it, because what we were shooting blew the GoPro over from the shock wave...
