I have H110 and Hornady 240gr XTP-MAG bullets. Most load data I have shows starting loads at 35gr for H110 or W296. I would like to load less than the starting charge for a velocity around 1650fps. Any load data to share?
My Hornady manual lists the 240gr. XTP-MAG bullet with H110 as
Firearm used 7.5” Freedom Arms revolver
Primer Federal 205
.454 Start load 34.1 gr. = 1600 fps
.454 MAX load 36.9 gr. = 1850 fps
FYI, the 460 S&W Magnum and the .454 Casull share the same SAAMI 65,000 psi (MAP)
Also, H110 can have ignition problems in low density charges and loads with low bullet “pull” (light bullet weights and light roll crimp)
Generally it is wise to not load H110 below 3% of maximum for proper ignition especially with lighter bullets.
I would use caution loading below 35 grains and use a SR Magnum primer and a heavy crimp.
