I just got my first crossbow, and I can definitely say that it is extremely fun to shoot. I picked it up used, but it looks like new and functions perfectly. My question is about the limbs. I noticed that they are not cranked down all the way. Should they be?? Also the guy I got it from said that I should shoot 22"bolts, but the guide says to shoot 20"bolts that way a total weight of 450gr's or more. Any help or input would be appreciated. Btw it's a Barnett Wildcat C5.
