I recently acquired a nice stash of older powders from someone getting out of handloading. One powder in the bunch has been discontinued --- Reloder 12. The canister is yellow and was made by Hercules. Alliant now produces the Reloder 10x and Reloder 15 powders, but not Reloder 12.
Has anybody used this rifle powder? What's it really good for? I'm looking to put it to good use, so any suggestions would be great.
