100yds. Wouldn't bet I could do it every time, got so excited I quit right there. That 1680 powder has been my salvation so far with another Hornet (bolt gun), my .357Max, and I'm starting work with it in the .44Mag Handi I just bought, as opposed to the faster powders that are conventionally used. It has worked particularly well in the Max with 190 gr cast, both GC and PP, will be working with PP in the Mag 44. GW
