Blasted WSP brass finish primers!! Installed another new firing pin to my Match Space Gun, took it yesterday to a Highpower rifle match, and before 44 rounds had been fired another firing pin tip is scalloped due to a pierced primer. 
Before you think I am running hot loads, I was using out to 300 yards was 69 Sierra 21.5 grains N135, Fed cases WSR (brass). This load chronographs at 2818 fps in my Krieger barreled Space Gun. I used a hotter load of 80 Sierra 23.5 grains N140 W/W cases and CCI 41 (mil spec primer) at 600 yards and never had a single pierced primer even though that scalloped firing pin tip creates a stress riser.
The good old nickel plated Winchester small rifle primers never ate up firing pins like these blasted brass finish primers; they are just too thin. I hate them.
Glad my last sheaf of them is down to 100 primers. I am not going to use them again, I have enough CCI 41’s and a sheaf of CCI 400’s to last a good while and these primers shoot just fine.
