    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.

    The .30-03 is simply a .30-06 with round nose (non spitzer bullets) Case dimensions are exactly the same. You just need to find the ammo it likes

    actually the case OAL was a hair longer than the 30-06. they shortened the neck and went to a lighter spitzer bullet like Robo said and went to a cooler burning powder. they only used it for three years before it evolved into the 30-06.

    OA Case length 65mm, vs 63.5 for the 30-06. The slightly longer neck and a BIG 220 g round nosed bullet puts the bullet closer to the rifling. Shooting 30-06 in a 30-03, long jump to the rifling.

    Speaking of which- what is the condition of the rifling?
