I have been reloading for a only a little bit, and I am wondering that I may be doing something wrong... On three of the six primers I tried they failed to fire on the first firing but all fired on the second fall of the hammer. 30-30 Winchester cases, BC-2 powder, the primers are CCI 200 large rifle. Is it that I am seating them to far in? Is it the primers? combination... Any help for a Newb would be quite appreciated!
