The battle rifles of WWI (some did) had sights out to 2,000 yards. Optimistic? Pretty much. I think that was mainly for volley fire, not at individual targets. Fifteen hundred yards? Probably the same thing. 1,000 yards? Still poking and hoping, with a rifle. Five hundred yards, and your in trouble. Inside of 400 yards with a Battle Rifle, (M-16, FN, M-14, M-1 or AK-47) and your toast, well done. Any kind of well made pistol, Colt .45, or clones, Ruger .45 or 9MM, Glock or Taurus or S&W, will put a serious hurt on you regularly at 50 yards. This "long range past ten yards" is tripe. My Daughter gets 9 hits with her PT 22 at 15 yards on a Transtar II target in less than 7 seconds. I TRAIN people to shoot at 25 yards that have never fired a pistol in their lives. They qualify. Shooting is about 90% mental, not physical. A standing, or even crouching Human is a big target at 25 yards. Don't limit yourself.
