Like the title says. I have been getting exceptional accuracy with 168 grain Nosler Custom Competitions and A-max's, but with the varget at 45.5 grains, I am worried that I am pounding on my rifle. Any thoughts?
 
Re: 45.5 Gn's varget+168's=too hot for my ar10?

That might be pushing it. In my gun I haven't tried 168s, but I have tried:

175gr SMK: 45gr was too hot, serious ejector swipes on every piece of brass. 44.2 is what I'd call max. 2580fps

155gr Scenar: 46.5 had swipes on 8/10 pieces of brass, settled on 46gr as a safe load. There are still some shiny spots where the ejector is on some pieces, but lots of factory ammo does this also. 46.2 is about the same but I stay at 46 to be safe. 2750fps.

This was with virgin Winchester brass.

Gas guns really are limited when it comes to max loads.
