My gf just got an 1895 Winchester marked for .30-03 ammo. I would like to find the dimensions of the brass; the case length is my question. The gun will shoot .30-06 they say, but the accuracy is not good. So, it looks like there will be some conversion of either .270 Win or .280 Rem to make better ammo. None of my reloading manuals show me anything about the .30-03 cartridge, so I am wondering if any of you have some old manual that gives that information.
