[QUOTE="Buano, post: 1928037, member: 21641"] One copper bullet issue you may not be aware of: Because of the lower density of copper compared to lead, the same weight copper bullet will be longer than its lead cousin. Longer bullets require a higher spin rate to stabilize as compared to shorter bullets, so a rifle that may shoot a 140 grain lead bullet very well may not spin the 140 grain copper bullet fast enough. For that reason some rifles will benefit from going to a lighter copper bullet to achieve maximum accuracy. [/QUOTE]
