Reloading for 375 Winchester using 30-30 brass

[greatwhite]

I started reloading for my 375 Winchester, but brass is very hard to come by. I was thinking of using 30-30 brass and fire forming. Will the fact that the brass is slightly shorter cause much of a problem?

I compared pressures and see the that the 30-30 can handle up to 41,600. The load I use for my 375 Winchester is 35 grains H4198 which creates a pressure of approx 38,900. So could I use this same load in the 30-30 brass? Can I use the same bullet.

Nobody has ever reloaded for 375 Winchester, wow.

Yes I reload 375 winchester and yes I have used 30-30 brass without trouble.

I'd certainly try it in a pinch - I'd also try 38 - 55 brass available from Higginson"s, which would need very little if any sizing an trim to the right length.

The length is not the issue. Once you form them you will want to trim them to a common length . However the case neck thickness may not be enough to allow for a suitable tight fit on the bullets. Try a couple of cases before you do a large batch. Cast bullets with larger diameters can help.
