Even though i don't own a rifle so chambered, I have been obtaining some 6mm Remington brass because it has been available. It seems that 7x57mm brass is hard to find lately, so today I reassured my self that I can form 7x57mm brass from 6x57mm brass. Necking up to .257 Roberts first made it very easy going.
I have 8x57mm brass, so I don't have to neck up that far.
