Is it better to go up from 6mm Rem, or go down from 7x57?


Going up is usually easier less chance of a donut or any need to neck turn, but check anyway. It can be done in one pass. 7mm to 25 might need to go 6.5mm first depending on the brass.

I just got 6mm Win. brass from Natchez for 20% off, might want to watch and see if they do another discount.


Isn't that backwards? Going up you have potentially thicker shoulder material becoming neck. Voila, donut. Going down it's neck material becoming shoulder.
