I tried 200 rounds with small rifle primers, no issues what-so-ever with the primers. One thing I didn't mention before that I'm curious to get some respones on:
With brand new starline brass, after loading ~1000 rounds twice I had two split cases. i.e. brand new brass, load, shoot, load again, shoot, 2 split cases in the second go around. Any thoughts on that? I wasn't expecting to have any split cases that quickly.
