My local gun club has ground hog shoots that are really a hillbilly version of Bench rest competitions. I am toying with giving the sporter /hunting rifle class a try. Weight limit is 10.5 lbs . Ranges of 100,200.300 yards Fives shots each. I am looking at a Ruger American Varmint, 223 or 6mm Creedmoor. Factory ammo abounds for both and hand loading is doable. Any advice advice/thoughts?
