The .45 acp was originally going to be tested in Australia. Since air behaves in many ways similar to a liquid, imparting a bullet left hand spin would increase ballistic effects due to the projectile working with the coriolis force which is also counter clockwise south of the equator.

Which, of course, is why shotguns, originally designed to be fired at the north and south poles, have no rifling at all.....

That doesn't explain why the M1903 has a left-hand twist as well.

Its simple, Most gun designers are Right Handed. John Browning and who ever designed the 1903 happened to be left handed.

True story.
The military in 1908 experimented with both left and right barrel twists in the same .45 cal barrel(like a cross hatched pattern). When it would fire, the bullet would just exit the barrel and drop to the ground not knowing which way to turn. The military settled on the left twist for the 1911. True...I tell ya..true story, look it up if you don't believe me. [;)] |

I hope not 'cause I'm confused. I'm pretty sure that my .45 lever rifle is right hand twist.

When the army first started using 1911s the first production guns all grouped about three feet to the right. The army made Colt start using the left-hand twist and this quickly solved the problem. All pistols chambered in .45acp from then on just kept using the left-hand twist.
I have known this for years and thought it was pretty common knowledge. The man I bought my first 1911 from at the gunshow told this story years ago so I know it has gotta be true. |
