Rifling makes the pattern very wide in everything but the smooth bore garden guns. The garden guns didn't get much traction because few folks actually have gardens in locations where a gun going off won't get a response from LEO.Sounds like it would be (ha! wood bee?). I've only fired 22-shot (we called it "rat shot") a few times, and don't really know how they pattern.
