Crossbow "BOLTS have a much heavier spine than arrows. Your average crossbow is strung at 150 pounds. That is a LOT of weight to transfer into a bolt. Shooting too light of a projectile can and more than likely WILL result in one or 2 things. Projectile breaking, limbs cracking. And quite possibly head cracking from a limb failure. So the answer is, absolutely NOT. You can not use a regular arrow in a crossbow unless it is rated for 150 pound or above as well as hard cam if the crossbow you are using the M4. Those cams aren't particularly "radical" but they are considered "hard".
