I took my Optima out with some 385gr buffalo bullets. 70gr bh209, cci 209m primers. Had 3 bullets into one little hole and one "yes the 5th shot!" an inch and a half outside that group.
I scoot back to 72 yards and it turns into a shot gun pattern!
One thing i noticed was a huge amount of tar building up at the muzzle from the lube on the bullets. 6 rounds was more than enough before i called it quits.
The lee minies do the same thing to me but ive come to feel that their problem is inconsistent bullet diameter.
Ahhhhh when will the big brown santa truck come with my bullets??
Im gettin sick here without being able to shoot accurately LOL.
