Very true. My .460 S&W mag shoots .45 LC, .454 casull, and .460 magnums. That is the order of slowest to the fastest, and the 45 is a good 6-10 inches higher than the .460 at 30 yards.

Thought it was more of a trajectory thing because the heavier bullets "rainbow" more. Larger bullets also work better with a less aggressive twist. IIRC
Probably takes more work to twist a heavier bullet.
