I see I am guilty of overgeneralization ... didn't mean to imply that every manufacturer used every one of the features I listed.
After seeing the pellet deformation in the Hornady test video, it's apparent those pellets are not hardened, plated or protected by buffering. I can't see any way Hornady wouldn't benefit from things that help their shotshells deliver rounder pellets on target, but...
I stopped using Hornady TAP FPD buckshot several years ago, because their crimps were so sloppy it was disturbing. I haven't bought any since, and AFAIK don't have any left. I still prefer Federal LE127-00 with FliteControl, till something better comes along.
Mindset - Skillset - Toolset. In that order!
Attitude and skill will get you through times of no gear, better than gear will get you through times of no attitude and no skill.
