I just wanted to say thanks for the tips. Based on Charley's tip, I went back and reloaded another 20 being very careful with the primers. Turns out the primers weren't seated properly before as I don't think I was getting them deep enough. I went to range and shot 12 rounds with no misfires. Thanks!

To 7mm.
I was using brand new brass this time and Winchester LR primers that are stored in the original box in a dry storage cabinet. I appreciate the tips.
