2-piper,

One can make a strong case that cartridge names often give only approximate information about the dimensions of the bullets, amount of powder and case lenght. One can suspect there is some of that imprecision in dimensions and specifics for shotshells. Actual chamber lenghts, hull lenghts, shotsizes, shot weights, etc. being some of the specifics that seem to often diverge from nominal.

Is there not some saying in English that "Consistency is hallmark of constrained intellects." ?
