Mike, I must disagree with you on this
I LOVE H110/296. I have burned well over 100 pounds of H110 over the last 40 years hand loading it in the 357 Magnum and the 41 Magnum cartridges and have spent many Range Days with a Chronograph capturing data
As to real world velocities for the 125 JHP, 357 loading with H110 (not test barrels) in a . . . . . .
2 1/8" Model 640 - 1234 FPS (AVG of 3 revolvers)
2 1/2" Model 19/66 - 1287 FPS (AVG of 2 revolvers)
3 1/2" Model 27 - 1315 FPS (AVG of 1 revolvers)
5" Model 627 - 1496 FPS (AVG of 2 revolvers)
6" Model 27 - 1531 FPS (AVG of 2 revolvers)
8" Python - 1599 FPS (AVG of 1 revolvers)
10" T/C Contender - 1780 FPS (AVG of 1 firearm)
18" Model 1982 - 2106 FPS (AVG of 1 lever gun)
These were strings of 5 shots per firearm all averaged together
I am quite pleased with the velocity from the J-frames.
Considering how often I used to carry a 3 1/2" Model 27 or a snub nosed Model 19/66 the velocity loss when carrying the pocketable Model 640 is not that significant
