Just a quick question on ammo for my AR. The twist is 1 in 7" and is a 16" Daniel Defense barrel. Am I ok to shoot the Black Hills 52gr moly coated hp in this or will the moly coat mess up the chrome lining? I've always had outstanding accuracy with this round in my single shot .223. Only looking at this ammo based on price $22 for 50 rounds and past experience. If it's a no go, no big deal.
