I'm working on forming 22 Hornet brass into 25 Stevens. It will be primed with an acorn 6mm Flobert blank. 55 grain boolit. Now what powder to start with? I want the velocity to be 1000 fps +/- 50 fps. Unique would be my first guess- ain't got any, ain't seen any, and don't expect to see any. I have 2400, 30-31, 4198, loads of 4227 and old formula Nitro 100. I load 38 S&W with 2 grs of Nitro, heavier bullet and I'm guessing less case capacity. Trying to keep pressure as low as possible maybe 4227? Anyone out there with quick load that can let me know if I'm even in the ballpark? Thanks Neil
