Your WCO may not be entirely accurate. According to a few sources, acceptable calibers for small game will be from .177 to .22, but for woodchucks and furbearers, air guns will need to be at least .22. While not as popular, there are some air guns in .20 (5.0mm).According to a local WCO, it seems that the possible coming regulations limit airgun use to .177 and .22 caliber...
(emphasis mine)PGC said:Air-guns for small game in calibers from .177 to .22 for small game, for woodchucks at least 22-caliber
I found no other information related to airgun caliber for furbearers, but if I understand correctly, airguns (presumably .22 or larger) may also be used to take furbearers that may be taken with a hunting license (e.g. coyote)? .22 (particularly airgun) seems small for a 'yote unless the muzzle is practically against the skull...PGC said:To dispatch trapped animals during deer season, trappers are limited to...or air- or gas-operated firearms that are 22-caliber.
I hear ya. But that's good for dispatching something trapped. My comments were more about hunting/stalking. For that scenario, .25 or (preferably) larger could humanely take a 'yote. My ideal would be something like the Hatsan Carnivore BT in .357 (also available in .30), with game at 50 yards or under. To elude rightful scorn of the PGC and traditional firearm hunters, among other things, airgunners will need to keep themselves sharp (lots of practice) and know/respect their limits. I view hunting with an airgun as more akin to bow hunting than traditional firearm hunting.Shoot a 'yote or a fox or the biggest coon in the ear (in line to come out the other ear) with a .22 or .177 pellet from an adult type rifle at trap chain length and it'll be dead before it hits the ground.
