I just made my first piece of 300 AAC Blackout brass, simple enough. I used my dremel to cut a pc. of 223 mainly just to see what was involved as far as trimming and sizing is concerned, I know there is better way to cut off the 223 shoulders. I am thinking a arrow cutoff saw with the length gauge set a little long and trim to corect length. What methods are you guys using to speed up the process and and all tips and pointers are appreciated.
