Good morning,
... I would not be surprised to see the results get better as the drum continues to be conditioned and break in. We often see the best results after a pound has been ran through any powder measure ...

As indicated by email from Calvin, I ran some W231/HP-38 through the Auto Drum with a new cone before conducting the 50 drop test. You can see that the elastomer wiper has blackened to be "conditioned".
Powder measure was reassembled with light pressure on the wing nut so there was no slop of cone. Hopper was filled with W231/HP-38 and lightly tapped 20 times to settle the powder. About 10 charges were dropped before starting 50 charge drops with target of 5.0 gr.
Creedmoor Sports TRX-925 digital scale was used after power on auto calibration without any warm up. Auto Drum was mounted in station #2 of 2023 Breech Lock Pro 1000.
