Always assumed it was to torque the firearm towards your hand, instead of out of your grip.

Coriolis effect. You need to make all of your shots west to east to improve the accuracy for long distance shots.

Correct, at that distance time to target will be about 4 seconds, you also have the curve of the earth, wind, temp and humidity....... The twist of the rifle has to be right hand for the math to work...... |

Colt pistols were/are left hand rifled. There is some BS about it being because a left hand twist will cause the gun to torque into your hand (rt handed shooter). The truth is Col. Colts first factories in the US were failures, so he moved production to London, where they rifle twist left, when he came back, he kept the left hand twist rifling. I think Kimber offers left twist in their 1911's.

Many old Colts were left hand twist and barrels I made for Wildey were left twist as well. We did that in the last 2-3 years of Wil's operations to attempt to counteract the annoying habit of his pistols ejecting the brass into your face. It "seemed" to be a benefit with that, can't hurt either way though.

It's mostly right handed because the bearings in modern flash hiders countersink in a negative way with left twisted barrels. If your upper reciever is contoured with a device that is technically named a dickfer it doesn't matter what rifling is used. Hope that clears it up for you.

It's really so the cleaning rod attachments like bronze brushes don't unscrew when pulling them through the barrel. This is a serious defect with British Enfield rifle barrels.

If you carried a special death AR, all you'd have to do is change out uppers. Or if you were tier one, have one of the quick change barrel set ups. I'd want to color code it though to always match the barrel spin direction to the correct spin cartridges. |

So that external ballistic phenomena that arise from the spin of the bullet don't happen in reverse if you are using a different gun.

If they operated east to west, there would be no way to get the bullet to drop enough due to the ~1,040mph increase in velocity due to shooting into the earth's rotation. The tier 0 guys calculate their distance to their westerly targets, adjust their elevation +45 degrees and shoot east. This way as the bullet slows down and the earth catches back up the bullet falls into the target. |
