"A reactionary of shooting" isn't clear English.  Google Translate's "rebound of shooting" isn't much better.  I reworded the English message under the assumption that the recoil from shooting the weapon affected the shooter (though that's something that seems more in consistent with a firearm rather than a bow or crossbow).  If it's a projectile bouncing off something and coming back to hit the shooter, then the message should be reworded.
