I think kenetic energy and broadhead type should play a role in this decision. For example: I have 74 ft pounds of KE. It may be acceptable to take that shot if using a fixed blade broadhead. However, with a mechanical broadhead with a 1.5 inch cutting diameter I wouldn't even think about it. What is your KE and what type of broadhead are you using? If your KE is on the low side forget it...noneed to think about it any further.Ask yourself those questions along with everything else listed here and you should be able to make a better decision. If you still decide to take the shot (with low KE) only your circumstances will change your decision for future shots.
