I'm really liking the rat shot idea and am going to give it a pop.
Better have tame squirrels, that you can walk right up to...
What's the useful range? 20 feet? If so, I'm in biz.
In my experience 22 rat shot works better out of a pistol than a rifle. The pattern is better anyway. A rifle barrel messes with things, unless it's a smoothbore.
I'm thinking 10 feet or less effective range.
