I chronyed a couple of loads shot thu my Raging Bull and have to say I'm a bit surprised at how low the velocity readings were :-\

load 1
23gr of H110 befind 245gr copper plated bullet, WLP
Avg. velocity = 1103fps ??? I was expecting around 1450-1550fps.

load 2
10gr of Herco befind 245gr copper plated bullet, WLP
Avg. vel = 790fps :eek: turned out to be a .44SPL load; I was expacting 1100fps min! Alinat lists 805fps from 7.7gr using 246gr L bullet


Are those the number I would likely get from any 6in gun or is (my) Raging Bull produces lower than normal velocities?

Are you sure your chronograph is reading properly? Shoot something known over it to test. I would think what you were expecting would be likely considering that's a pretty warm load.

More crimp will increase pressures, but you won't see anything dramatic, don't think. I've never played with that, though. I don't shoot .44 mag. Buddy had a super blackhawk and loads W296 in it with good results. H110 is normally listed as a good powder, though. Might try some AA#9, great powder for heavy .357 loads. I load 2400 in my .45 Colt for heavy .44 mag equivalent loads, but the .44 doesn't do as well with 2400 as with 296 as I recall.
