My limited chronograph data:
1.2gr Red Dot, 73 Grain ACME Bullet- 498, 532, 451, 515, 494 FPS
Random assortment of vintage BP rounds (likely featuring 80-90 projectiles): 653, 620, 631 FPS
One BP round of my own creation, with the aforementioned ACME bullet: 725 FPS
All rounds were fired through a solid-framed H&R 733, with a 2 1/2" barrel. Just for those who might be interested, 2.7 grains of Red Dot in a 32 S&W Long case, from the same revolver, propels a 100gr SWC to nearly 900 fps. I've had alot of fun playing around with the 32 S&W short and Long. I did get ahold of some 71 grain, 32 cal HP's, and made a few 32 S&W short "Defensive +P" rounds. I seem to have misplaced my notes, but it was over 2 grains of Red Dot. Fired from an SP101 for safetie's sake, It had the same recoil and muzzle blast as a stout 32 long. Unfortunately I failed to get a good chronograph reading.
