I am not sure what to think of this I was using fed 205's forming some new brass I got about 4 of them that didn't fire out of 15  .
The primers were indented so I loaded up 20 of the remaining primers in my 22 br tried them and no missfires is it possible I don't have enough spring tension I know ppc's are set weak to begin with .
I have never had issues before with this gun and I also had the bullets tight in the lands there should have been no issues with the case jumping ahead.
