Our 300blk brass is all formed from 1x fired Lake City cases.

As with all brass, final inspection is to be performed by the person loading before loading the cases.

All the brass has been:

Washed (our liquid tumbling process)
Deprimed
Swaged (every 50th piece is checked with a Ballistic Tools primer pocket gauge for uniformity)
Trimmed to 1.360 (shoulder set is started in the trimming die)
Finish sized to 300BLK SAAMI spec (every 10th piece is checked in a Sheridan chamber gauge for uniformity)
Chamfered and deburred on a Giraud trimmer to a 1.358 OAL +/- .003 (this is why our 300BLK brass shines, most companies just stainless tumble which beats the burrs down, or charge an additional fee for Giruad trim)
Polished in our high shine corncob mix
