another false shoulder question - 08/31/14
I am going to make .280 RCBS casings out of .270 Winchester brass and I have a couple of dies to bring it up to 7mm and a .308 winchester die that I think that I can use to bring it up to .308 and then use the .280 RCBS die to create a false shoulder, then fire form. Is there another die that I could get to bring it barely above 7 mm and not work the brass so much? Could I just go from .270 to .308 in one step or is two necessary? Only other time that I have made a false shoulder I was going down all of the time. Has anybody tried to use a Lee collet die to step up the brass? I have lots to learn. miles
