How many firings do you get with your 30-378 Weatherby brass?

Len, I get between 6-8 with the heavy loads. I anneal the neckes every 3rd time, partial full length size just to fit the chamber. I've never had a problem with neck splits, usually just how the primer feels when I seat it, determins when to pitch the case.

Len, that depends how "hot" you reload,going over maximum ,one time reload. Without signs of pressure , 5 to 10. Have you found a good load for this caliber.
