Nick, Et al;
On several sites that sell Mil-surp powder they claim that for WC 846 you can use BL-C(2), or Win 748 load info.

In some cartridges (223) BL-C(2) and Win 748 are VERY close to the same thing. Some others, not so much.

Do you know if WC 846 is the Mil version of BL-C(2), or Win 748?

I went through a bunch of powder MSDS sheets at one time. I can't recall if it was one from Hodgdon or one from St. Marks (I think it was the latter) that indicated BL-C(2) is the same thing as WC 846, except that WC 846 would not be canister grade, so the burning rate could be somewhat higher or lower, depending on the lot. Start low and work up carefully.

Thanks I appreciate it!!

Here's the complete collection. I left out obsoletes, like Winchester 540, but that could be guessed from the military and OEM name if somebody had some:
