Hadn’t ever really thought about this until today... there is not a whole lot of crossover between revolver, semiautomatic, or rifle bullet diameters, but there are whole bunch that are crazy close. I know some of it can be explained by metric/English differences but even then it's kind of arbitrarily different. There is no reason a semiauto couldn’t shoot a .357 bullet instead of the .355 that a 9mm is. 25acp is .251 and the 25caliber rifle bullets are .257. 32 caliber pistol bullets .311 or .312 but 30 caliber rifle rounds are typically .308.
This just doesn’t seem sensible. Must have been figured out by politicians.
