I have been looking at getting a bushnell 6-24-50 scope for ranges out to 1200 yds. Is this too much of a scope for that range? I have been doing some reading in the stickys. I came across and article that said that a scope in 3x - 17x power range better cope with the effects of mirage. Is this true? Should i try to find a scope in 15x to 17x Range for up to 1200 yards?
