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?

Thanks,

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.
Good Luck

Change to 250 gr hornady xtp?

If you change to hornady 250 gr xtp ,here is Hornady specs from vol #4.I called them on this and this is what they sent me.


250 gr 30 gr = 1450 fps
30.5 = 1500 fps
31.1 = 1550 fps
31.7 = 1600 fps
32.2 = 1650 fps
COL is 1.685"
Sectional Density .175
BC is .146
Dia .452
Bullet Part # is 45200

I use Win 296 31.5 gr runs about 1575 out of my raging bull 6.5 barrel
Hope this helps

Update: 34.5 gr of H110 under Hornady 240gr XTP-MAG in .454 Casull brass worked well as a "light practice" load for my .460 S&W Mag.
