I use 2500+ from white label lubes.
It really works.
I shoot 325 grain cast in my 45-70,forget what the speed was but hogs don't like them.
So far no deer.
I cast my bullets for rifles with ww and lino for a little more toughness.
They are gas checked.
Slower get plain base.
I got tired of changing lube between pistols and rifles so i use it for everything.
