A few spins by hand and its done.
I then uniform the primer pockets, so its part of my new brass routine.
I've done hundreds of ex mil sup 7.62x51/.308 brass that way.


I have the Lyman deburr tool for small primer pockets though. At $7-9 its sweet.

I tried the 5 cutter countersink last night, I de-burred this 1943 / 1942 quite heavily on 2 and that wasnt enough.....reluctant to deburr any more...
