Steve,
Thanks for the research on PPU!
I'm fortunate to have a pretty good stock of PPU 22H ammo. Picked it up when I couldn't find brass in 2021. I had just gotten into the 22H thing.
Cases seem robust. I have had some primer flow issues on a Savage 219b in 22H though with some factory PPU, which surprised me for I've not experienced that before with this rifle. So suspect the factory primers. I have a spare 22H barrel for an early 219 that I need to see if I get that same issue. No issues with that older 219 with 30-30. Both rifles have small rifle firing pins. Thus suspect the primers.
Anyway, should be resolved when I reload.
