I love your reasoning. Why use even a 22 for meaningless noisemaking when you can noise pollute cyberspace with your keyboard, GK.andy said:so what? Why not just use a .22, since it's just meaningless noisemaking, anyway?
Now to your point. Most hi-power shooting isn't plinking but serious practice of one kind of another. Most of it involves paper targets because many of the civilian ranges that I am familiar with don't allow metal reactive targets because of safety considerations. Thats a shame but you have to live with their rules of you want to shoot.
