Trim 6.5 Grendel brass BEFORE or AFTER sizing to 6-whatever ?
#6
I trim after necking down and then again after fireforming. All my trimming is done with the RCBS Trim Pro power case trimmer. If you buy the 3 way cutter you can trim a truck load of brass very quickly all to a uniform length and it comes out chamfered and deburred to boot. If you don’t use the three way cutter you will still need to chamfer and debur in separate operations.

If you already have the RCBS trim pro or trim pro 2’s they sell the power head and base separately as a unit. It’s one of those things that makes you choke at the price but kick yourself in the pants for not investing in earlier.

All you need for the trim pro is a 6mm pilot and 6.5 Grendel case holder plate.
