Thread: Weird Cartridge Nomenclature

Welll... Here we go again. The .22LR, that lovely cartridge, is .223 cal. The .22WMR (Winchester Magnum Rimfire) is .224. They are not interchangeable in .22WMR guns. Why? Mostly due to cartridge taper, although the teeny little 1/1000" diameter difference gets into the act. Question is, why on earth did Winchester, & why would the firearms manufacturers, tolerate a newly-introduced .22 (WMR) round that didn't allow the use of .22 shorts, longs & long rifles? I mean, this was a while back, somewhat before everyone on Earth expected corporate executives to be lyin' cheatin' thieves. Seems like a really dumb decision. Any thoughts?

The .45 colt vs .45acp has less of a craziness problem. Bullet diameter (lead bullet; subtract ~.001" for jacketed) is .454 vs .452. You could pretty much swap'em. The big difference is in cartridge length. The Army wanted a grip-fed semiauto & you'd have to have pretty unusual hands to hold something like a 1911 in .45 Colt.

However, the .30/30 was a .30 (well, ~.308-.311) caliber round developed after the advent of smokeless powder & was never commercially loaded with black powder as far as I know.

The .30-30 was originally called the .30 WCF.

A few months after Winchester brought it out, Marlin copied it and introduced it as the .30-30 for the 1893 rifle, using the standard convention of the weight in grains of the powder charge, only this time it was smokeless powder.

Winchester kept the .30 WCF on the headstamp up until the '40's, then changed it to .30-30. Today we call it the .30-30 Winchester, but it was actually Marlin that introduced it under that name.

Why are rounds designed by John Browning called "automatic COLT pistol?"

Ever noticed that most of Browning designs don't carry his name? Colt 1911; Winchester 1892; ACP instead of ABP (automatic Browning pistol)...etc.

Here's a tangent: one of the most famous guns to carry Browning's name was actually not his design, the Browning Hi-Power. It was completed by Dieudonné Saive at Fabrique Nationale based on Browning's design.

Because he designed them for Colt.

The High-Power design was started by JMB, but finished after his death.

He designed guns for Remington, Winchester, Colt, FN.

The Browning Arms Company wasn't formed until after his death. He never really did much in the way of manufacturing on his own, but he was a design genius.

He also marketed them in Europe through FN.

But only the one that he didn't finish carried his name. Isn't that weird?

He was GOD of firearm designs. No man before or since has equaled his genius. I don't think anyone could ever equal his prolific output in firearm designs.

I think FN actually produced them before Colt did.

Don't forget the BAR.

That's right, the BAR! One of the finest automatic rifles of all time. I would love to have one, or even fire one, in full auto mode.
