I dunno, I take moving squirrels and rabbits at 30 yards with my 10-22 and I don't think 00 buck has the same penetration as .22lR at any range other than point blank.
You know how light skinned refrigerator are, right, well, I found one abandoned in a shooting are a few years back, had most of my arsenal with me, and was currious as to what would penetrate it?
At 20 yards, "everything went through" EXCEPT 00 buck.
So don't yell at the movie screen the next time you see a refer stop a shot gun blast. Hollywood would be getting that one right.
