I don't trust Environ Metal the makers of Hevi Shot. Maybe they are better now but there was a time when their product was very sketchy. Pellets were often globular in shape rather than round, their diameter was all over the place and inconsistent, weights/density varied highly and the material matrix was occasionally so brittle that it powdered upon impact. In their loaded ammo they would change hulls, powder, wads, ect. with no notice given to the consumer. So after doing meticulous testing with various chokes to find that perfect combination Hevi Shot would change the components in the shell and patterns would go to hell. It was maddening.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
