I made 7-08s from PPU 308s for my sons H&R single shot. They worked for 3 loadings. The fourth the action was slightly hard to close and brass was a little sticky. Not enough to really even notice until all 20 were fired.
On the 5th loading now and the action has to be snapped closed and the brass is very sticky.
I was neck sizing only for all previous loads, but FL sized when this problem showed up and the action is still hard to close on an empty case. All brass was trimmed prior to loading the dummy.
Using the same die on the same day I formed a Federal 308 case and no problem. Action closes easy.
My problem is I don’t have that many LR primers to fire form the federal brass, and am hoping someone has some Insight on what I should do to make the PPU brass work. I’ve got 2 kids to get ready for deer season and a handful of primers.
Thanks
