Just ran across a sizeable supply of SRB-118 ball powder. The little data with it suggests it is something similar to WC-844 or WC-846, or AA-2230... Does anone know for sure if the ame powder has been sold under another name, for which there might be dependable loading data?

WC844 and AA2230 are in the same ballpark, but 846 is more in the BL-C or 2525 area.

Looks like the prudent thin to do is payy all shipping costs and deliver it to my house for disposal.
I have not seen that designation for milsurp/OEM powder,but with the limited information I think I would shoot some begining AA 2230 loads across a chronograph and see how your data compares with the listed velocity data.

The little factual data I have (printed on the container labels) seems to indicate it may be a bit slower burning than 2230...it recommends 27.0 grs of it with 69 gr. bullets in the .223....

I have already used roughly 24 pounds of it in the .30-BR, shooting from 29.0 to 30.0 grains of it under 210 gr. cast bullets with no problems.

Was looking to see if it had another identity so I could more easily develop loads for it in a number of other cartridges. It's always nice to be able to start out with some known minimum loads. Digging in my stash yesterday, I found 32 pounds of it I had forgotten I had, so figured I might as well load up some other stuff with it as I no longer shoot cast bullet benchrest.

AC,
