What are common causes of Primer malfunctions. I had 4 of the last 50 shells I reloaded fail to fire. The firing pin dented the primer but they did not ignite. One was on a Whitetail buck!! Luckily my first shot had killed him and I was just trying to follow up.
I use a Lee hand tool now and am careful not to touch the primers. The rifle is a Ruger MK II 7mm mag SS. I had a problem years ago trying to put primers in using the press it self. I thought getting a handtool would ensure this miss fire thing would end.
