What powders has everyone used in a 260 Rem? I know its not a real popular cartridge, but figured a few of yall have used them. @Shooter64 told me he used H4350 when I got the gun from him, and I have some of that powder, but will probably run a slightly heavier bullet plus would love to use ball powder if possible. I have some H380, BLC2, and Win760 on hand. If velocities won't compare prettt close, then I'll just use the H4350 if needed.
