Haven't used minies for very long time for hunting . If your shots are close , like 100 yds. or less , and you can compensate for the minie's inherent , in flight, rainbow , go for it. Minies I used were the .580 , bore sized Lee target minie. It was deadly accurate on paper. I foolishly sighted my peep sighted Harpers Ferry rifle in @ 100 meters , because the shooting range was 100 meters and the rifle rendered a consistent 3 and 1/2" group at that distance. However ,due to the thin skirt of that particular minie , I couldn't bump the powder charge up enough to flatten the trajectory to eliminate the 6+ " rainbow in mid flight. Soon as I boosted the powder charge up to about 80 gr. to try for flatter trajectory , blown skirts were the result. Back then , there were no FORUM'S to ask for help , so I sold the rifle and went to a flat shooting .50 cal. long rifle...Killed several deer w/ the .58..Boy does it put ''em down.....oldwood
