So I just got all my stuff for casting and loading for my 45-70. This is the second time I am using a gas check. I had no problems running them through the sizer and getting them to seat on my 44 cal stuff.
However,
My 45 cal stuff is not so user friendly. My boolit is .460 and my sizing die is a Lee .460 sizing die that I got from Ranch Dog. My gas checks go on real easy and after going through the sizing die they come off just as easily, what is the problem.
