Was it the .220 Swift?



From Wayne Van Zwoll:

What of the 6mms? If the .223 is too light for pronghorns, why is the .243 approved for elk? At 3,150 fps, velocity for the 55-grain .223 bullet equals that of a 90-grain .243 bullet. Muzzle energies: 1,200 and 2,200 foot-pounds. But a bull elk outweighs a pronghorn buck 6 to 1.

We think of 6mm (.243) cartridges as modern. But the first of them appeared in the 1895 Lee straight-pull bolt rifle. Also known as the .236 Navy, the 6mm Lee Navy was a semi-rimmed round chambered in about 15,000 military rifles. Its 112-grain bullet ambled along at only 2,560 fps but could have been driven much faster had modern powders been available. That bullet was very long; rifling twist was 1:7-1/2. The 6mm Lee Navy died in 1935. Shortly thereafter, the .220 Swift was born of the same case.

You got it. The .220 Swift is the only caliber I know of based on a 6mm Lee Navy case. See where it says parent case in the box on the right side of the page. http://en.wikipedia.org/wiki/.220_Swift Most people don't know the Swift is semi-rimmed, even some people who shoot it. One guy was really surprised when I told him that about his own rifle. The rim is the same diameter as the .30-06 and over 100 other calibers, but the body of the case is skinnier.


The .243 Winchester is based on a .308 Winchester case and it's rimless, not semi-rimless, but thanks for playing, guys.  ;D

To make it easier to load. Think "fouling" and "muzzle-loader" and you get the picture.

Check this from Wiki pedia
http://en.wikipedia.org/wiki/6mm_Lee_Navy

It does not mention the .243, that came from a site I found about the Spanish American war, but I can't find it now.


The 6mm served as the basis for the .220 Swift, which used a necked-down 6mm case. That's what I was talking about.  :)

Yes, it was done to prevent fouling of the barrel from lead build up giving the shooter more loads between cleanings of the barrel.  The first rifled barrel dates back to about 1498-1500.  The increased accuracy achieved was purely by accident as are most great inventions.

Yep. One day at work he showed me his .45 Professional cartridge that the 450 is based on. It's made from .284 Winchester cases cut off at the neck. He was making .475 Wildey Magnum cases from .284 and had a flash of genius - make it as long as possible and stick it in an AR-15. And he said that Gene Stoner told him it wouldn't work.

Here's a hint. It's equal to 28 inches. Now you know it's not a yard or a meter.
