First, let me apologize if I dumped this in the wrong forum. Should that be the case, feel free to take a moment to kick the newbie and slide the post wherever it may need to go.
I'm wanting to load something around 300 gr lead at 1300 to 1500 fps in my braked 15" 460 S&W Encore. The idea is to find a fun load to slam rams at 200 meters in IHMSA. In my first attempt at silhouette I managed to do well with a 44 mag and 250 gr lead. My thought are that the longer and heavier .452 will keep their velocity and not drop too much more than the 429 mag.
One thing I've discovered is that nobody has any mid-range load data for the 460. It's either subsonic Trail Boss or big boy loads.
If I try the suggested 1800 fps loads I'll end up with velocities approaching 2000 fps and it'll be a bit stiffer than I'd care to shoot all day.
Hodgdon lists Varget and H4895 loads for similar weight lead in a 45-70 pistol. The pressures are about 1/3 the capacity of the 460. Is it safe to work up something like that?
Should I look at 454 Casull loads with a case filler? For those not familiar with it, the 460 has a larger case capacity than a 308 and works at a higher pressure.
Something that makes velocity easier is the fact that I don't have a cylinder gap. The factory Hornady 200 gr (gasp!) jacketed loads rated at 2200 fps in a revolver leave my barrel at 2700 fps.
The Trail Boss loads I've tried don't quite have the velocity I want. The 250 rnfp are leaving around 1200 fps with 12.5 gr TB. While that would be great for indirect fire, I'd like something a little flatter than the St Louis Arch.
Naturally, I'm not taking this barrel too seriously in the matches. Instead, it's something that I would have fun playing with.
I'd appreciate any info you'd have to offer.
Thanks,
Kevin
