You should be fine. It's nice to have your broadheads hitting the same as your field tips though, that way your arrows are flying true and straight (i.e. better accuracy, deepest penetration, etc.). As long as your broadheads aren't steering left or right at any given distance I believe you have a pretty good setup IMO. Most deer are taken less than 25yds anyway and as long as you are deadly accurate to your self imposed max. shooting range then I say you are in great shape. However, if you are getting silver dollar groups at 20yds and do well to 25yds what's keeping you from taking a shot at 30yds at deer sized game? Do your groups open that much larger at 30?
