I don't know anything about caliber. How is a caliber designation determined? Why doesn't the 9mm cartridge have a caliber designation like the 45 and 40 caliber round, etc.?
Bill, to best answer your question You would first need to put a point in front of that .45, or .40 caliber designation. Because they are fractions of an inch. .22, .32, .38, .357, etc..... The europeans measure theres in millimeters. 5.56mm, 6.5mm, 8mm, 9mm, 10mm, etc.... Shotguns are measured in bore gage,not caliber. [ except for .410 bore, notice the point in front] If you took 1 pound of pure lead and divided it into 12 equal parts, and formed one of those parts into a perfectly round ball, that would be the size of a 12 bore gage. It works the same for 10, 16, 20,28, and 32, gages etc.....
Does that help? DR
would not have sounded right.But being this is a .43 Magnum, the most powerful handgun in the world and would blow your head clean off, you've gotta ask yourself one question: "Do I feel lucky?" Well, do ya, punk?
