I hear what you guys are sayin' about the habitat, but that's not an "absolute" imo. That might be the case, but I'd eliminate this one first....odds are that Bob has no choice about habitat looking at the pic. Bob, I like the idea of a .22 also (heck, I'd use my .22lr and wouldn't think twice about the noise), but please take a couple of practice shots with the ammo you'll use from the approx. distance you'll be shooting from to make sure you'll hit where you aim with a strange gun. That's why my LEO tennant missed. He shoots a LOT, but .223s and .308s, etc. from several hundred yards out, and not a .22 short at 50 ft. Bottom line, make it count...if in doubt, #6 shot
. Good luck!
