I live in Braselton (extreme N Gwinnett) and I have a big field in my back yard that is probably on the order of 15 acres or so. Lots of deer and other wildlife out there---along with some rather large coyotes. This week they have been very active and just this morning I saw two out there---both about the size of a medium German Sheppard. There are a lot of small kids in our neighborhood and plenty of pets. These guys have no fear of people and actually get pretty close to my back fence---maybe 50 yards +/-. I would like to find a buddy that would loan me a .22LR with a can to snipe these guys out... is that enough bullet or would I need more? Because of location, I need it to be QUIET. Ideas? Traps?
