I'm shooting the above rifle in 45 colt cal. and even with different powders (mostly slower) am finding the cases with heavy black streaks on one side. Is this normal? Do I need a faster powder or maybe a harder crimp to start with..
or a larger bullet. The groove dia. is .452 the best I can tell. It likes the .454 cast wheel weights best. Should I change something or just clean the empties..........Thanks folks ........catch
