Yeh, never try to consider "labeled" to be technically accurate. I have often wondered if some of this came from the transition from linen patched black powder bullets. As if a .311 ball wrapped in a patch did fit a .32 bore. Without SAAMI, etc during transition to smokeless, lots of room for various ways of expressing dimensions. Just a thought.....
As far as always buying the biggest and fastest, Cowboy, why buy an 8 passenger 450HP SUV when a 5 passenger 265HP Crew cab PU is all you need. I love my .22RFs and shoot them the most. Pleasant to shoot, test of my skills for accuracy. I'm glad for your interest and your question. Happy shooting. |

Turtlehead, its this one...

The reason many of our handgun rounds don't match name and actual bore size is due to the development history of cartridge ammunition. The reason our modern .38's are actually .36s (.358") for instance, is because the early cartridges were actually .38s. They used a heel type lead bullet (like the .22LR still does today). The full diameter of the bullet (bore size) was the same as the diameter of the case. Later, bullet design changed, the inside lubricated bullet (the lube & the widest part of the bullet were inside the case) was superior to the heel type bullet. But, this meant the bullet was a little smaller than bore diameter. Not a big issue with soft(er) lead bullets that upset and fill the bore well. Later, when harder bullets and jacketed bullets became the general standard, new gun bore sizes were reduced, slightly, for the best bullet to bore fit. Of course there a lot more to it than just that, but that's roughly why our 38s shoot "36s" and our .44s are "43" (.429). The .45 Colt didn't go through this, having come along after the era of heeled bullets. However, even the .45 Colt has been changed a bit. Pre WWII, the usual bore size was .454. Post WWII, through today, its usually .451/.452". Rifle rounds went through their own changes, for many other different reasons. There's books about this stuff, I like reading them. You might, too.
