I'll be moving to another house in a month or so. The previous owner said he has had rattlesnakes in the backyard which backs up to a greenbelt preserve (with coyotes and wild ferral hogs in the area as well) , 3 under the deck, and also some copperheads in the front yard. These reptiles are not there all the time, just once in a while. Thinking about carrying a sidearm during the summer months when in the backyard. Will a 22 with ratshot work OK?
