460 S&W with rifle powders?

[CGT80]

Has anyone tried rifle powders in their 460 smith revolver (460 S&W xvr 8 3/8"), for a medium power load?

I have run a 240 grain bullet with win296 to 19xx fps and have run a 250 grain bullets to about 1000 fps with trailboss and a 200 grain bullet to 11xx fps with trail boss. I would like to fill in the gap between those loads. I am new to big revolvers and the win296 loads seem a bit too stout to run more than a handful per range session. The lighter loads, including the 45LC loads I have made up, are fun but quite mild out of this gun.

I have 250 grain Rainier plated bullets, 240 grain sierra jacketed, and 240 grain hornady xtp mag bullets. I also plan to cast for this gun and have 225 grain RN molds which I used for 45acp in the past. I am considering a lee mold for a RNFP near 250grains. I wasn't sure if I should bother with a gas check bullet (how fast can I run without a GC?) I will use white label carnauba red lube.

I think AA 5744 would fit the bill nicely, but I would have to order it. I have h-335 and IMR 4895 on hand. I read a statement by John Ross, that these powders would be safe in the 500 S&W, but I have not heard of anyone using them. He has a good reputation, but I don't want to make any costly mistakes.

Thanks Guys

IMR-4227 would be the only one I would try if it was me.

I have looked around and www.hodgdon.com has heavier bullet loads, using H4198 "rifle powder" but nothing in the burn range that you were thinking.
Unless you have expertise that we're not aware of, I would avoid trying to use untested powders for your own safety.
The 460 S&W magnum is a great round when loaded correctly, and if you plan on cast bullets, I recommend going to a heavier slug so velocity is kept down a bit, and you wont need gas checks. Just use appropriate powders like Hodgdon Titegroup or even Alliant Power Pistol at www.alliantpowder.com.
Usually keeping velocity under 1600fps will keep leading down. You can't do that safely with W296/H110, because they aren't designed to be downloaded too much.
I have no experience with AA5744.

I've used 4895 and 3031 in a .500, they work, I got about 870FPS with a 450 gr cast / 6.5" bbl., using 42 grains or so. Lots of unburned powder on the snow in front of the gun, turns the cases black as pressure is pretty low, as i recall the SD was OK but not great. Reasonably clean (use 748 if you really want a mess). Seems like a 460 with heavy bullets might be a bit better suited to these powders than the 500.
