I’m interested in making 300 blackout out of 223/556 range brass. I know some manufacturers brass is too thick in the “new” formed neck for the 300blk. Therefore, I am looking at a neck turning set up for this (and maybe other 30cal rounds). Would anyone care to share what is good and what to stay away from? I probably won’t convert more than 2k-3k rounds. I will need everything associated with turning—tool, cutter, mandrel....
Thank you!
