It's a start.
Took my new-to-me rifle to the range last Friday. At the end of the session I wondered if I had wasted my money.
Went to town and bought some thicker patches and tried again on Saturday. I went home happier. I started at 25 yards because I had trouble staying on the paper Friday. I picked the best two sets and took three more shots at 50 yards. I think I am close to the "sweet spot". Have to adjust the sight a little but I am getting close to a decent group off my homemade rest.
