I really don't care what DawgFvr thinks can or can't be done at long range with open sights, but it does bring up an interesting point. Many people (mostly non-shooters) think it's impossible to hit anything past 100 yds without a scope. I can't tell you the number of people I've talked to whose jaws drop when you explain a Highpower match to them. In fact, I just took a guy from work shooting over the weekend and taught him the National Match course of fire. He has done plinking before, but never past 100 yds. At first, he thought it was incredible that anyone could hit anything even at 300 yds with open sights. By the time we finished, he was a believer.
