OK ive been buisy for the alst few days. I live in PA and we have very similar weather. I normally just wear a set of thermals, and pants and shirt, and a jacket for hunting. I do make sure i have enough hunting clothes for sitting in freezing weather but i normall just use it for coyote in the snow and when its cold and rainy. As for a gun a 243 would be plenty for gun for there actually you could get a 20 gauge shotgun combo with both smooth and rifled barrels and then you would be set to hunt anything. I doubt youll get many shots over 150 yards. I will recomend finding someone that hunts and letting them teach you about shooting and gun safety thentaking you on your first few trips into the woods.
