I have seen people on this site claim they shoot under 1" groups at 500 yards. I do believe there are people no this site that can do it but I don't believe it is as many people that claim they can. I have read people shooting under one inch at 500 yards with a factory stock rifle. Is this really possible? With my 20x Leupold scope the cross hairs look to be about 3" thick on a target 500 yards away. How much talk is straight BS here?
