I agree with the fact that with todays new bows and equipment that the effective range of the bowhunter has definitely changed. The best innovation that has increased the bowhunters range I feel is the laser rangefinder. I feel comfortable taking deer out to 30yds with no concerns. I also feel that under certain circumstances a 40yd shot is not out of the question. This is all provided that you practice shooting at these ranges as much as you do for a 20yd shot. I have one question for some and that is why is your effective range different in open areas as opposed to wooded areas? Wouldn't you be effective in both? I would think that open areas would be less because animals tend to be more on edge when in the open and less relaxed. That would be the main factor for me as far as how long of a shot I would take. I would be more apt to take a longer shot at a relaxed animal than a animal that seems a little nervous and timid.
