Looking for 244/6mm Remington brass, new, once fired or loaded ammo.

I've heard it can be made from 257 Roberts. True ? How ?

Thanks!

I do not have any 6mm. But it can be made from .257 just neck it down and then fire for to you chamber. 7x57 can be used as well. you could even use 8x57 if you have a 7x57 die to start necking it down. There are probably other combos but that's all I can think of. Watch out for the donut when necking brass. I would work up a new load with the new necked brass

The .257 Roberts and the 7X57 are the same case with a different neck diameter and shoulder angle. The .257 is easy to make into 6mm brass.
But I assumed someone with your vast experience would know how to do that?

PM sent.

found some thanks !
