 Is there any advantage/disadvantage from a manufacturing, physics, engineering, or shooting perspective for a right-hand or left-hand twist in a rifle or handgun. The only thing I can think of is that since most people are right handed and that a firearm will rotate opposite of the direction of barrel twist, a right-handed (clockwise) twist would tend to force the gun's grip to rotate into the strong hand. Enlighten me.

| No perceivable or proven advantage over the other. As far as torquing the barrel to tighten, the math runs that it would be a fraction of a foot pound of force, and over a very limited amount of time. It would never overcome thread tension in either way. As far as bullet drift-- no perceivable or proven advantage- either way. |

Enlighten me.Ever see pictures in the gun rags of magnum handguns under full recoil, I.E. the muzzle up, gun rolled to the left ? LH rifling counters that twisting effect for R/H shooters. |

Any torsional effects of rifling are negligible. If a gun is canted in recoil it's due more to body mechanics and photogs wanting a cool shot that actual physics. |

If that is meant as an absolute then I have to respectfully disagree at least if is meant to apply to all guns.
My 1911 ( LH twist ) does not roll to the left while my 9mm Browning Hi Power ( RH twist would like to. Also please observe these.40 caliber Glocks in slo motion. I submit that they tend to roll left though fired by different shooters right and left handed. https://www.youtube.com/watch?v=tMUbUoU-HA0 https://www.youtube.com/watch?v=QV6vGQLu0u4 |

Large diameter, heavy projectiles at magnum speeds can most certainly "roll" a gun, though it will still usually be a smaller component than grip mechanics. |
