Well I am a fairly good shot out to 50 yards but I do not practice at that distance too often. I guess it would depend on you and your equipment? I have a 27.5 inch draw at 65 pounds at 264 fps. I am not sure about the KE but I am guessing that it is in the 60's. So I am going to say that my max effective range is 35 yards, personally. Although, I see guys at the range with a 32 inch draw at 70 pounds shooting lasers out to 60 yards all day long.

I guess dirty Harry was right, a man's got to know his limitations.
