I would, but none available here at this time. Wallet comes home this afternoon (I hope).
I found some 7mm Mauser and .257 Roberts brass in my 'stuff'. I was able to get the .257 brass sized to fit, but not the 7x57 brass.
I need new brass in .257 Roberts or 6mm Rem.
I suspect even the 7x57 brass will have too thick necks and need outside turning. This rifle seems to have a minimally sized chamber.
