Have some 385 grain 45-70 bullets, need some loading data

[bobotech]

I have a bunch of 385 grain cast bullets that i want to load.

I cant find any listings for the powders that I have. I have IMR 4198 and IMR 4350 that I would like to use.

Heck, I even have some of that odd military surplus rifle powder that I will probably never ever use: RAD-78L-(7383)

Any suggestions?

None of my books list loads for my powders.

Lyman #49 lists:
Ruger #1 loads:
A 385 cast with XMP-5744, IMR-4198, N130, XMR-2015, RX7, H332, and Varget.

Trap-door loads:
SR-4759, XMP-5744, IMR-4198, N130, XMR-2015, RX7, IMR-3031, and Varget.

Hodgdon lists:
Trapdoor loads:
A 385 cast with Varget, IMR-4064, IMR-4895, H-4895, IMR-3031, Benchmark, IMR-4198, H-4198, and Trail Boss.

IMR-4350 is too slow.

Without tested data, RAD-78L-(7383) is lawn fertilizer.

what 'level'ar u wanting to load them to? trapdoor,marlin,ruger?

Marlin or lower. Its a Cowboy lever.

This would be more for range fun loads, not hunting loads.

BTW thanks, RC, I went to hodgen's and found the trapdoor loads. I didn't think to look there. I don't have the Lyman book.
