[QUOTE="rscott5028, post: 553378, member: 24624"] Great points. I'm not sure I could do justice to the history. But, a lot of the old cartridges evolved when bullet construction wasn't as advanced. Hence, twists were slow (e.g. 1:12 for 257 WBY vs 1:10 today) because a 257 WBY would have shread the old bullets with a fast twist. Now that bullets have evolved along with slower burning powders, you can push the longer/heavier bullets to higher velocities with a fast enough twist to stabilize them. -- richard [/QUOTE]
