it seems new 6mm brass has become impossible to find , excepting a few gougers on gunbroker .
with spring nearly here and summer around the corner i need some new cases or else my trusty 788 is going to miss yet another summers groundhog hunting .
so it looks like forming cases from 7x57 is on my plate , so a nice simple question from those in the know .
what worked out best for you ... inside reaming or turning the outside of the neck ?
