[QUOTE="Paladin300, post: 2787592, member: 115299"] I understand that but we are talking about inches in barrel length and stabilization of heavier bullets. In theory if you could increase the number of revolutions a bullet took before it left the barrel while increasing the speed you could stabilize a heavy bullet in a long slow twist barrel but the barrel say in a 1/10 twist would need to be 30 inches or longer and you would need to push it extremely fast which would also increase the barrel length. For practical purposes say barrels less than 30 inches you need to increase the twist not the barrel length. Barrel length is about velocity and when you increase velocity you increase rpm’s but not significantly enough to effect stability in a slow twist barrel. I understand the formula I am just trying to put the cookies on the bottom shelf so he can understand that increasing barrel length with in usable perimeters does not increase stability which was the question.
