As with any kind of shooting, hours of practice is extremely critical. Shooting is a degradable skill....use it or lose it as they say. Point shooting is EXTREMELY important if you are CQB. I would agree that it is not that effective (as a standard practice) beyond 20 meters or so. Though I do admit to trying to do it beyond 100 meters, just because. I think everyone should practice this skill. You hear everyone always talking about SHTF scenarios...well, where do you think most of that will take place. Urban environment, clearing a building, searching buildings for food, supplies, etc.
