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 .
