I have re-barreled my Model 12 .308 with a Criterion barrel and put in a Rifle Basix trigger. Went through a ladder test and bullet depth determination using Sierra 175 grain bullets, Lapua brass and Federal Match primers. Shot it recently at 200 meters the best group being 1.355" which would be a .594 MOA at 200 meters. Would you be O.K. with this or should I be looking for better performance?
