What is the minimum arrow weight that I can shoot from my crossbow?

If you are shooting a Wicked Ridge or TenPoint crossbow made prior to 2012, the finished arrow weight should be at least 420-grains total, which includes a 100-grain field tip or broadhead. 

If you are shooting a Wicked Ridge, Horton Crossbow Innovations, or TenPoint crossbow made in 2012 or after, the finished arrow weight should be at least 370-grains total, which includes a 100-grain field tip or broadhead.  

EXCEPTIONS:  The Wicked Ridge Ranger, Lady Ranger, and Ranger X2 crossbow models can shoot arrows that have a finished arrow weight of at least 350-grains, which includes a 100-grain field tip or broadhead.
