I load all my .30-30 stuff on a set of Redding dies but I've always liked those Lee factory crimp dies for a couple other things that I reload. Then; Lo and Behold, I came across a Lee crimp die for .30-30 at a yard sale some years ago. Things seem better for my .30-30 loads since I started using that crimp die in a separate step. Discovered the same thing reloading .22 Hornet also. Even do the Lee crimp on 7.62x54R ammo for an old Mosin-Nagant but haven't as yet noticed any big difference on that one. But then, I'm still in the early stages of load development on that cartridge.
