I just found a coffee can full of 500 gn. 30:1 plain base slugs. I've used them in BPCR shooting, in my 45/70 . I'd like to work up a load for these in my .458 Win mag. Looking for 1300 fps or so. My barrel is only 22" long or I'd load'em up with 3f Goex. Looking for some modest smokeless loadings...any ideas...???
Thanks,
Don

the 458 winny mag can also be called the 45-2.5 belted . it fits right between the 45-90 winchester and the 45-100 sharps. there is alot of smokeless data for these cartridges .
try starting @ 42 grains of IMR 3031 or 35 grains of IMR 4198

I imagine a full case of WC 860, with a few grains of kicker, would put you about where you want to be. And, it's cheap!

Or you might start with about 25 grains of Accurate 5744.

I was going to suggest 25 grains of 5744, but you see I'm a day late and a dollar short.

Oh, what the heck, I'll suggest it anyway.

24 grs. of 2400 should do the trick. Clean burning and meters well
