If someone can place three shots in a one inch circle at 100 yards with a .30/06 - 150 grain Remington Core-Lokt bullet, at what type of distances will the logic that leads one to come to the conclusion that he can place three shots in a 2 inch circle at 200 yards, a 3 inch circle at 300 yards, etc. hold up as long as the shooting is done under good conditions (from a rest on a nice, clear day)? This is assuming that that person isn't experienced at shooting at longer ranges. I don't have any way of shooting at longer ranges to test it for myself and I am curious. Is this a difficult question to answer?
