[QUOTE="Varminator 911, post: 1230597, member: 9705"] The one inch or less gain for lead core is probably because too much gain would overly stress the jacket. Whereas a copper solid won't be ripped apart by the change in twist. And some solids only engage the drive band. So the bore riding part of the bullet won't be affected at all. For Berger bullets stick with a constant twist. The needed twists are easily available. Using a gain twist with one inch of gain would make no sense to me. [/QUOTE]
