I just thought I'd pop this up here. I'm a big fan of those Hi-Tek Cowboy #3 projectiles so I decided to make some load data.
Using Unique powder, CCI Lg pistol non-magnum primers and seating to the crimp groove (I'll mic these tonight, I forgot to do that), chrono at 5' from muzzle,here's the current 10 round group average numbers I got:
5.0 grains Unique from my Charter Bulldog- 637 fps, 118 power factor.
Everything else from my S&W 629 4":
6.0 grains Unique- 794 fps, 190 power factor
6.7 grains Unique- 870 fps, 208 power factor
7.5 grains Unique- 918 fps, 220 power factor
