and when you've got it about as good as you can get it , get into LOAD DEVELOPMENT- or at least try different factory ammo and SEE what the rifle likes best- just keep the bullet weight limits in mind- way back when we could use them my 3 guys all liked a slightly different recipie, and all three of them would put a 20 round mag into a twoonie sized group at 100 yards with no fliers- off a bench and bipod mind you,with a 4x-12 scope- my factory norc will do that as well, benched and weighted properly-
