[QUOTE="Wallie, post: 3051798, member: 107256"] I think possibly it could matter, like in the picture in post #3, which side of a rifling is affected. Like gears in a mechanism, there is a “load” side and a “coast” side. If the bullet is getting shoved out the barrel by 60,000 psi in a right hand twist, after the bullet jacket is initially scribed into the leade, the right side/face of the riflings would resist forward motion and force the bullet to twist/spin, but the left side/face of the rifling is more or less irrelevant I would think. Since barrels never have to operate in reverse! [/QUOTE]
