Well despite how well it meters the HS-6 still has an issue: so much unburned powder. Soooooo much. The various loads were:
255 Grain MBC Keith SWC Hi-tek over
9,9.5, and 10 grains of HS-6 (Lyman 50:
8.8-10.3 grains)
300 Grain Hornady XTP over 9, 9.5, and 10 grains of HS-6 (Hogdon Website: 9-10 grains)
All loads had Winchester Large Pistol Primers (what both sets of load data called for) . Gun was the 4.2 inch Redhawk 45 Colt/ACP. It was maybe 32 degrees at the range (doubt that helped).
So my best guess is to switch to some explicitly magnum primers and work up the loads again, but I would greatly appreciate any feedback from my gun forum guru's on the issue.
