thanks for posting!

Just tonight I tested some Herco loads in .40 S&W. At 95 degrees, they came in 20 fps OVER the advertised speeds according to Alliant. Accuracy remains undetermined, as I didn't "fluff" the sandbag and wound up with the grips on a hard surface for two of the five shots.

Flash report: Herco has a medium orange glow about the size of a hardball, of fairly short duration. IME, Power Pistol flashes almost white and much brighter.

BTW, I believe that Speer's data runs hotter because so many of their bullets have slippery and slightly thicker copper jackets, and 3% antinmony cores, which results in less frictional "slugging" as the bullets accelerate down the bore.

At what distance were you getting those 1 inch groups? That .357 SIG is catching my interest again.
