I'm loading for 30-30 WCF. I've got Large Rifle primers handy, but they are the 7.62 NATO kind and they are a coinflip whether they go off or not, as they are too firm to use reliably.
Could I use Large Pistol Primers instead for 30-30? It's a relatively low pressure rifle cartridge, and I may be able to just skirt by using them.
Using factory 30-30, I've noticed complete reliability with my primer strikes. On the other hand with the 7.62 primers, I've had far too many light strikes to use them again in the future.
