Depends on gauge but I have always used the .22 short, long, and long rifle for most furbearing animals on a trap line. The .22 mag, 220 swift, 6mm will take care of the larger ones. The shotguns make too many holes in the pelt which decreases the value.
i hope its a 16 or 20 gauge. a twelve gauge will blow the crap out of a small animal. if u just shoot to kill it wood be ok. but if u want the firs or meat u would use a .22 or a pelletgun over 1000fps.
When hunting whitetails there are many different languages being spoken afield that I key on when outdoors. All these little creatures living around whitetails have something to tell us if we are willing to listen.
My favorite tattletales of the outdoors are a handful of little birds that live in my state of Ohio. Maybe yours too. A tip for the upcoming season.
There are Blue Jays, Cardinals, Chickadees, Killdeer, and Sparrows that all have language...
