Well I picked up 100 new 45-70 pieces of brass from Starline. I read online that this brass will actually shrink during the initial firing?? Should I wait to trim till after I use them? Should I go ahead and resize them? Should I resize and trim before using? What's has everyone else had luck doing? Random length checks show they are kind of all over the place. Within spec but not uniform.Thanks again for the help.
I have always used previously fired brass for my pistols, so this is my first time buying brand new brass and new brass for a rifle.
