I've reloaded a small batch of Missouri 165gr whitetails. I loaded them on top of 16.5gr of imr 4227 fed 210m primers and fc brass. I haven't shot cast bullets out of 30-30 yet but i figured 4227 was a good start as i have been told it is the "go to" for cast. Now the problem is, i have a hell of a time to keep them in a 5 inch group at just 35 yards! at first i thought i was having a bad day of offhand, but when i benched it, the groups didn't change. now i know i can shrink the groups up with changing my loads, but I've never had that large of a group to start especially with a suggested load out of the lyman book. has anyone else experienced this with the Missouri cast bullets in 30-30?
