What did you do in the reloading room today?
Tried out Power Pistol as a replacement for Unique in .38 Special under Lyman 358429. Worked 4.0 grains up to 5.0.
Good accuracy at 25 yards but high standard deviations. At 5 grains the 10-shot spread was 794-850. The lighter charges varied even more.
Also tried Clean Shot, a Czech powder. 3.7 grains under the Mihec DeCarli wadcutter, seated & crimped in the groove. 2.5" groups at 25, Average around 850 FPS. Approach their published data with caution. Their starting loads look +P
