There's only 2 flies, but very BIG fliesin your statement-to begin with, you're ASSUMING ANY H&R slug gun will perform exactly as your's does, AND as you well (or SHOULD) know, not every slug gun will always like the exact same loading. Don't get me wrong, I'm tickled you have such a nice shooting setup, but there's NO way in hell that every slug gun of exact type/brand/model of mass produced quality will produce exact same level of accuracy as yours does or even shoot same exact load as well.
