Has anyone tried loading with mixed powders? I have about a pound and a quarter of various powders that I've collected over the years, HS-6, IMR 4895, H-4895, Unique, WST, H-110, and wondered it it could be used for anything. I used to lube bullets, and if I pulled them and lube got on the powder, I would just toss it into an empty powder can, which is now a full powder can. The black hodgdon ones.
If one were to develop a load out of this stuff, how would you go about it?
Or, should I just keep it for SHTF...
