Does anyone know how it came to be that the diameter of a .22 cal bullet got to be .223? The closest thing to an explanation I've seen was the phrase "for technical reasons."
I understand that some cartridges seemed to be named (or numbered) after the case, and some after the bullet, and that some are marketing invention. What's two or three thousandths of an inch? You would think an American company would have gone for .220 or .250. Does it have to do with the diameter of bore, or the rifling?
Inquiring minds, and all that....
