Here is my 325 gr. plain base Gould, factory HP.
It cast at .4605" with ACWWs.
I'm anxious to shoot this one in my new 45/70 also.
I cast about 75 of these today. They will be sized .460" and lubed
with
Ben's Red and BLL.
It is a real killer and doesn't need 1,600 fps + to be a killer on deer.
It works well on deer at 1,200 - 1,400 fps :
