I have loaded about 30 rounds in the past week and I have had 3 shells where the cci200 have not ignite. After the first 2 I figured it was the primers being old so I bought 2 new boxes and I had one fail to fire. I don't have a problem with the same gun and Winchester work which I have shoot over 50 in the past 2 weeks. I haven't check my firing pin clearance, I need to find what it is suppose to be
Anyone else have this problem?
