Making brass

[mr.big]

Start with 202 pieces Lapua 220 Russian, neck it up to 6mm, turn necks to .011, ream flash holes to .062, run in tumbler a couple hours , prime with CCI400 primers, charge with 27.0 H322 and seat a 80 gr Sierra soft pt bullet.

Alls left is to shoot them all through an old barrel and I'll have a new batch of prime Lapua 6 mm PPC brass to use on the next new barrel that's just itching to be screwed on and tuned in.

How do you ream the flash holes, drill press? You build something that holds brass in place? How did you arrive at 062?

They come .060 +/- .062 is supposed to uniform them and clean up any burrs on the inside.
