What does one do to fix once-fired brass that is too short?
My particular problem centers around .450 Marlin brass that is too short--from the factory! We're talkin' 2.070-2.078 when it is supposed to be trimmed to 2.100...
The reason that I'm calling this a problem is that it throws off every other part of my reloading...these bullets are going into a tube-magazine and need a crimp. Thus, a case that is too short puts the crimping cannelure too far out. I can shorten the cartridge OAL but that kinda defeats the purpose of having a prescription for the load...not to mention that it likely changes the pressures.
Any advice on this one? Throw out the brass?
