I am getting sub 2" groups out of the 45 cal minie. The last time I went out shooting I was having trouble at 150 yards. I dropped the powder from 80 to 70 and shot a group. It was not good so I bumped it to 90 and presto. I shot a 3" group at 150. I went back to 100 and I have the same 2" groups or less I am looking for with a peep sight. I need to test the 150 again and go to 175. this was my last group I shot. Ron
