I just picked up a new barrel, .221 fire ball. It is a 10 inch octogone and looks like it was never fired, no wear marks of any kind. I shot 12 rounds of factory ammo through it at 25 yards just for fun. It grouped about 2 inches with open sights once it settled down. Shots started low center (first 3) then went high left (last 9). I know this is no real test of the barrels potential. Is any one else shooting this round? what is the best i can expect from this barrel? any pet loads i should try?
thanks.
