Watched Gerhardt slabbert's video. Hopefully I spelled it right. Anyway, I heard him stipulate that H&N are using a "proprietory" mix to gain the max on expansion. Now , I'm not here to crap on H&N. But emperical observation says "What is softer than Lead?" Now I'm sure their T BAR design will help in accuracy with the winds, BUT, better expansion? their pellets are known to be harder than JSB. I can't speak for their slugs, and If I'm wrong , I will be willful in acknowledging my mistake. As of now, I see it as a gimmick.
