Today I Loaded 30 rounds of CFEBLK Powder under Berry’s 220gr plated bullet with 3 different loads.

CFEBLK 11.0gr
CFEBLK 11.5gr
CFEBLK 12.0gr

Components Used:
300Blkout Case Head stamped WCC 12
Berry’s 220gr Plated Bullet

Each powder throw was weighed on two separate scales
Hornady GS350 Electronic Scale
RCBS 5-0-5 Balance Beam Scale
Both Scales were calibrated with an RCBS weight set before using.

All rounds would be fired from the bench at 50 yards from two rifles:
Ruger American Ranch Rifle in 300 Blackout

There was no feeding or extraction problems. In the AR15 each load locked the bolt to the rear after the last round.
