The Point of Ammo

Caliber is the approximate diameter of the bbl

45 cal   .451/1000 of an inch

38 cal / .357

9mm developed in Europe, metric .355 diameter


44 mag  .429 dia

Gauge vs. Bore

Gauge is determined by weight in fractions of a pound of a solid sphere of lead with a dia equal to the inside dia off the bbl

1/12 # ball fits in a 12 gauge bbl so 12 gauge


Except 410 which is a bore size of .410 inches but it would have been a 67 gauge although was at one time called a 36 gauge
