I just bought one myself, recently got done with barrel break in. I was very pleased with the first groups i shot at 250 i tried imr4831 and h-1000 got best results with the 1000 53 gr. behind a 140 berger shot four shot into .75 in. at 250 i may work with seating depth to see if i can get better, but i am pleased with that. My seating depth is 3.190 it is to long to extract an unfired case without taking the bolt out but who cares if it shoots that good
