As other have said, those 55gr FMJs in the AE aren't real conducive to accuracy. I should know, I cheaped out and got a takeoff .223 barrel for a trainer to use on my Rem 700 I run as a switch barrel. 1-12 twist so won't stabilize anything heavier than the 55s. I've put about 6k rounds through though (handloads) and in load dev it shot 5 round groups ever so slightly under 1 Moa (25.2 gr BCL-2 in Rem case with CCI400s) but average more along the lines of 1-1.25 moa. Plenty fine for positional practice though, makes the 1 moa gongs a real challenge, haha.
