These are the two different shooting sessions, COAL is set at mag length out of a Tikka T3 SL. H4350. Thinking I should start seating bullets deeper and see what happens. Should I try with-in the powder charges???
What cartridge? I'm assuming 30-06? I'd try IMR4831 instead. Went through the same thing with my rifles. They seemed to prefer that powder with that bullet. Your target pics are small, hard to see, although it looks like you have some 3 2 groupings there, which suggests the bullets need to be seated deeper..
