RE: How far will you take a shot?
Blaze orange dots and 3-d targets can't smell or hear and rarely try to jump out of your way. I can smoke targets at 40 and 50 yards, but too much can go wrong with a live animal at those distances.
30 yards is my max, and even then it would have to be pretty perfect conditions (wind, angle, deer position/attitude, etc.).
Consider this - if you see a shooter at 40 yards and don't take the shot, you'll be excited and ready to get back out there next time. If you DO take the shot, and things go BAD (wounded deer), how are you going to feel then???
Good luck
