That is some damn fine work, right there. Very nice job on that rifle.

You are SO busted...

Based on what you're saying, have you compared pressures between 6.5 Creedmoor and .260 Remington? Do you know the differences, in operation, besides what you posted about the external cartridge-case dimensions? Having said that, with pressures being almost identical... why have I not seen this in any .260 Remington that I've loaded - besides those hot 130s that I loaded up?... I posted a link to them... I'm using a .308 BCG, not a 6.5C BCG. I should be seeing the same things you're seeing, if what you're posting is some kind of "evidence..."...

@TeleStratMan, is this a 1969 Fender Rosewood Telecaster? I just saw this for sale for $16k. Since all guitarists play guitars, then everything is a 1969 Fender Rosewood Telecaster, by your mentality. According to that, THIS is a 1969 Fender Rosewood Telecaster, too... I found this for $31.02 on walmart.com... Gotta be the same, since all guitarists play guitars. Right?...

@TeleStratMan, the amount of butthurt that you've displayed about your nomenclature "willful" ignorance is amazing. It's not just "ignorance," because you state that you DO know the difference in the platforms. So, you're doing it intentionally, or with zero regard for what is correct - you don't care. The amount of butthurt based on the backlash is coming from the "I don't care" attitude, and your atempted defense of it- which is just stupid. You can continue to stay here- you don't have to leave, and you don't have to have someone "ban you." That comes up more often that you know, when people get caught in this kinda shiit. You can stay... But, since you already state that YOU KNOW the differences, then abide by the REAL nomenclature of the differences in the platform. Don't be lazy about it. If you think all three major platforms are the same, and "they're all AR-10s because there are only two platforms - AR-10 and AR15," as you state - they REALLY prove my point that you're correct - and buy a Rock River Arms Lar-8 upper and pin that thing to your Aero M5 (DPMS-based) lower. I just want to see pics of you possessing both, and trying to make it work...

You didn't educate anyone here with that - we've been posting that for years here, to educate people on the differences. You just didn't search before you posted, and thought you'd found some kind of informational "gold mine." You didn't. What you posted is, literally, old news. Except to you... Here's another one that pre-dates what you're posting, and Troy Ind was the first company to address the DPMS "high/low" change. This was about 2010 or 2011. We've used this one alot... There's even a write up on it on the main informational website, here (not the forum). This was posted to the main informational site(s) (308ar.com AND 762ar.com) at the same time as it came out. https://762ar.com/dpms-a3-handguards/

I just HAD to fix this for you, because you messed it up. I just clarified it for you. Tell you what, man, buy your Aero M5 Carbine recoil system (the complete set that they make). It will come with a buffer that's too light (at 3.8oz). You really need a buffer that's about 5.4oz - and there's an AR-10 Carbine buffer that meets that weight. Buy that Armalite AR-10 Carbine buffer, stick it in your setup, and report back what the results are. I can already tell you what the results are going to be, but just humor me here. You know, since you have an AR-10, anyway, and calling it by what it really is - just really isn't important. I'll be waiting...

I love me some horsepower - but it's just a number that's only derived from Torque calculations. It's measurable, but only from torque readings over time. These two right here - are just badass...

Nice looking setup, and well done. Just so you know, though, and it's discussed as common knowledge here - that's not an AR-10, not even close. Armalite makes the AR-10, and it's a completely different platform that the DPMS LR-308-based Aero M5 that you have. For example, I'll say this - pin an Armalite AR-10 upper receiver to your Aero M5 lower, and see if it fits. It won't. There are 3 basic platforms for these "larger ARs," and they are Armalite AR-10, DPMS LR-308, and Rock River Arms LAR-8. There are tons of different specialized platforms as well, but those are the three main platforms. So, just so you know, you don't have an "AR-10" in the least. Confusion amongst the platforms will only screw you over in the future, when you're looking for upper receiver parts and such. That's the entire reason that this site is named ".308AR.com" ...

I like that on a scale of 10, it's a 12...

Go home at 2 with a 10... Wake up at 10 with a 2... Beer Googles FTW...

You still sending Hornady your data on their defective ELD-M tips that dent and break when chambering?...

No need for them, if you need Armalite-length gas tubes. Just buy the Armalite gas tubes. Custom gas tubes is where they shine, and nobody else does that besides them - and gets it right. They do. They shine is a WHOLE LOT of other areas, in custom guns and quality parts, but you don't "have to have" a WOA gas tube to make your gun run. Glad to see you using their real name now, instead of just calling them "Oak," like you were before... See what you have first, brother, for a gas tube length. See what you need...

Is that the Alexander Arms barrel, 9/16x24 threading?

I did all that, building the load. I went as high as I could go on that original 18" gun (first Grendel) and made the load. Accuracy node at 28.5gr // AA2520. After that, I saw some pretty severe pressure signs before I hit the next accuracy node, so I stopped and called it there. Next Grendel that was up was the 12.5" build, and it was a beast. I thought I saw pressure signs with the exact same load (already had my load, so test it in the new short gun). At that point, I backed the load down to the next lower accuracy node, and that was 27.5gr // AA2520. I thought I was running hot ammo before, so I backed it down. Next node was exactly 1.0 full grain lower (original 18" gun). Then I built another Grendel, a lighter 18" gun over the original Mk12-ish heavy gun. 27.5 did good, brass still looked like the first 28.5 loads I made. Then I built a 16" M4 Grendel - brass was the same. Then I built a 16" Mk12 Mod H Grendel - brass looked the same. When @Matt.Cross and I had the chance to run our 18" Grendels (his is a Mk12 Mod 1, and mine is Mk12-ish) through a chrono, with HIM running factory Hornady Black ammo - he was smoking me by 150fps... WTF... At that point, I re-looked all my brass pics, load data, and reloaded some of those original 28.5s again, and ran them through the same chrono. Lo and behold - the numbers I reported above. It wasn't pressure signs I was seeing, with all 5 Grendels doing the same thing to brass - it's just what Grendels do to brass. I'm back on 28.5 grains, and it's worth it. There's no need for me to go back and reload everything up again, between 27.5 and 28.5 - I've already done that in the original load development. I'm not concerned about what load charge the 18" passes up the 16", on the way up again, because the accuracy between 27.5 and 28.5 was garbage. For me, that's just gonna be a waste of powder and projectiles - and time. There were zero cycling issues on any of the 5 Grendels, from 27.5 through 28.5. None.
