[QUOTE="J E Custom, post: 327190, member: 2736"] Typically fast twist do this if the velocity is high or in the case of the big magnums if you use a lite bullet and push it to fast it will/may shed the jacket. Example = Take a 223 rem and place a 40gr bullet in it at max pressure and fast twist (1 in 7) and you wont have any problems, But take the same bullet and twist and chamber it in a 223 WSSM and you will almost assuredly shed the jackets. Also big bores .375+ normally have a slower twist because of the starting shear of the big bullet is much higher than a lite one and they will tend to strip the jacket as Locknload said. The trend is to faster twist but that is for the heaver bullets in a caliber for stability and if you want velocity and lighter bullets you need to slow the twist down, This phenomenon is not to common unless a person pushes the envelope .
