There is really no such thing as a “crossbow” broadhead. They are just broadheads. If your speed numbers are to be believed, the real bow produces 77 Ft/Lbs. of KE and the xbow produces 80 Ft/Lbs. Any broadhead made will kill with either setup and will penetrate well (in excess of what is required for small animals like deer). The rage will be just fine so long as the blades don’t deploy upon discharging the crossbow. Most importantly is to practice with those broadheads to ensure proper flight and accuracy. Shooting at a deer for the first time is no time to discover how they fly and where they hit.
