I fireformed some 9.3x62 from .30-06 using 6gr bullseye, a tissue wad and a caseful of cornmeal. I don't have a lot of bullseye left, but I do have Unique. I'm thinking of doing the same load with Unique, any reason why it would'nt work?
I want to make them up and blow them out as I'm sending the rifle off to get the bolt bent and I want to make up at least 50 rounds before it comes back.
