What surplus powders will work in the 450?

[BD1]

The surplus powders I'm currently using, listed by how I use them, as follows:
WC820 - Lot# 47321 used primarily in the .44 mag and .357 (surplus from 30 carbine loadings, current lots load similar to AA#9))
WC852 - Lot# 47287 used primarily in the 6.5 x 55 (surplus from 30-06 loadings, this slow lot loads like 4831, fast lots load more like 3031)
297 - Lot# 16 used primarily in the .450B (new production OEM mag handgun powder, a grain or two slower than 296/H110)
HPC-18 - Lot# 93-003 used primarily in the .45acp and .38 special (surplus .45acp from Thompson SMG loadings, loads like 231)
WC680 Lot# 47269 used primarily for very heavy bullets in the .44 mag, and to a lessor extent in the .450B, I think this was surplus 7.61 x39 loads like 1680)

I've also used a good bit of WC860, (surplus 50 BMG), However, I don't have any with me in South Carolina as it is too temp sensitive for the south. And I own a jug of surplus #7, (surplus 12 gauge), which I rarely use as it meters so poorly.

I'd be happy to answer questions concerning the lot #s above if you happen across any of them.

Of the surplus powders on the market currently, the 297 that Pat's Reloading is offering is the the one with the broadest application in the .450 Bushmaster.

Here are the sources ofsurplus that I've used in the past:
