wolf LP primers. I just received a 1000 primers from PV and loaded up a 100 rounds using once or twice fired brass(400 corbon) and 700x. Around 15 or so(maybe more) didnt ignite the first time but did on the second. I also bought WST and wanted to work up a load in it, so I used new brass since it was my first time using this powder. No failures to ignite using new brass and wolf primers and WST. This leaves me wondering if the primers got seated deep enough. While I did tumble the brass clean I did not clean the primer pockets. I've never had this problem with cci or federal primers,even with dirty primer pockets. I guess I need to start cleaning the primer pocket/flash hole better with wolf primers.
