I just want to get this off my chest. Modern crossbows shoot arrows and not bolts. Arrows have fletching and bolts do not.
Ok, I'll shut up now.
This is a crossbow bolt:The crossbow bolt is a short dowel-type projectile that was once used for indoor and outdoor target shooting. It is seldom, if ever used in the twenty-eighth (or so) century of crossbow shooting. Now is time for crossbow shooters, arrow and crossbow manufacturers and even those opposed to the existence of crossbows to all crawl onto the very same page and come to the realization that the crossbow shoots arrows, not bolts.

Ok, I'll shut up now.
