It has been shown by experiment (painted pellets and high-speed photos) that damaged pellets, largely from bore contact and rear-of-load setback forces) are the laggards. This is predicted by aerodynamics also.

Hevi-shot is an interesting phenomenon. Teardrop-shaped pellets should have less drag than spheres, for the same streamlining reason that boat-tails are used on bullets. Evidently this generally outweighs Hevi-shot pellets' other shape "flaws."

And I too truly appreciate Miller's ability to assemble and provide great amounts of specific, documented information!
