Where I hunt, a long shot is about 40 yards. Thus, I’m not terribly worried about wind drift or arrow drop past 50 yards. So I’m going to use a heavy arrow that delivers maximum momentum without going too far overboard. With the online calculators and the array of options for arrow shafts and broadheads, tweaking arrow weight is a pretty simple deal. If you hunt areas where shots longer than 40 yards are the norm and you can see real benefit from increased arrow speed, it may make sense to sacrifice a bit of momentum, so long as you keep in mind that the farther an arrow travels, the less energy it retains. You may hit that elk at 70 yards, but will your arrow retain enough momentum to do its job?
