What can you do with one? Well, unless you're in the military or a sworn law officer, you can't shoot people. But if you get one in .223 or .308 you can shoot in Sniper Class matches, and with the .223, light up prairie dog towns. In .308 or .300 Win Mag you have an exemplary beanfield rifle. Some makers, like Montana Rifles, offer chamberings such as .260 Remington, 6.5 Creedmoor, and 6.5/284, which will enable you to compete in F Class matches, where you will learn more about shooting under pressure, doping wind, and achieving real long-range accuracy than anywhere else. Or you can simply shoot for fun. Remember fun? It's very far from tactical, but it's worth trying.
