Well, I didn't say it was a sure bet! Just a better bet than doing the same with a bow. That said, my USP45 Tactical is capable of accuracy in that general range. Although I'm usually not!
I do burn between 200-500 rounds a week, rimfire through centerfire. In my youth I shot rifle and pistol steel and some pinshooting. Overall I'm pretty handy with a rifle or pistol but you won't see me winning Top Shot anytime soon.
