Hoot,
The necks may have to be turned/reamed, depending on the rifle's chamber.I have an aversion to shortening 9.3x72R cases for this and other cartridges.This is a "generational"thing I think, because I'm old enough to remember having to struggle to find even berdan primed 9.3x72R cases. Cases are easier to find now, but I still prefer using 38-55 cases in the original length, rather than the current 30-30 length cases.Even though about 1/8" short, I would use 38-55 case and just seat the bullet "out"and center the case in the chamber( also for 8x57r/360, 8x58R S&S,and 9x58 1/2R S&S).Starline makes the longer cases, for those that don't have old ones.
