Not sure what he has to say that hasn't been said. Simply put, stay under 52,000psi! Also, they marketed it as a long range cartridge...Maybe some people think so because it's about as close as there is from an AR15 but I wouldn't consider it a good long range cartridge and particuarly at 52KPSI. The cartridge is best with light bullets..ala, 6PPC but people are simply trying to make the best of something in an AR15 platform that was never a good long range choice. Like virtually every comparison of cartridges, boiler room makes heavy for caliber bullets shine. A 6ARC lacks enough boiler room to be at its best with heavies. Yes, it might still be near the best from that rifle but it's just way down the list of viable 1000 yard cartridges. It just is, but it led people down the road of pushing it harder and harder until the platform showed its weakness. Personally, I think it'd make a lot of people smile from ear to ear at the right pressures with lighter bullets and at shorter ranges, with good bbls and well set up AR's. But again, the platform shows its weaknesses. It's still probably the best semi-auto rifle in terms of accuracy out there but you have to respect that it's not a bolt gun and it's not a 6 Dasher or similar either. If I were gonna play with one seriously, I'd look at 90-95gr bullets and at 600 yard stuff, but that just me. I think it'd shine best with still lighter bullets but of course, they don't shine well consistently, even at 600.Johnny's Reloading Bench on youtube has an entire in depth series on reloading for it. He's entertaining and a fellow KY boy. Give it a watch:
It's a good tool though and I don't want to seem like I'm bashing the round nor the rifle. They are both very good but by nature, I think we ask more of a good thing than it's intended for at times.
That's just my two cents and I'm not looking for a debate. Everything I've said has been proven over and over. Just use it in its wheelhouse and appreciate it for what it's really best at and keep the pressures down in that rifle platform or live with the possibilities and potential danger of lugs breaking. Otherwise, at best, you're still well behind a 6br bolt rifle in performance. Now remember this, I'm a huge fan of the 6 Grendel at short range with bullets up to 80gr and from bolt actions that let that puppy scream. Just a different animal at 70kpsi than at 52K but don't try that in an AR and I'm not recommending it in any rifle. As always, work up and stop before seeing pressure.
