Re: Berger and barrel twist
The faster you spin a bullet the more stress you place on the jacket and there comes an RPM that will cause the bullet to disintegrate. There is a line of reasoning that suggests that highly spun bullets with really badly stressed jackets will expand very easily and rapidly upon impacting game. This may be beneficial or it may be detrimental to a hunting experience. There have been a number of thread recently on impacting game with high speed thin jacketed, low SD bullets. Bergers have a thin jacket while the accubonds have a thick jacket made of a different alloy.
