Flat nock or half-moon?

I own, shoot and like my Horton 175 Hunter. It has 22" aluminum bolts (Easton 2216's) with the half-moon nocks. It shoots well and I've taken a few whitetails with no trouble at all. Recently however, I had an opportunity to pick up the new Wicked Ridge Invader which shoots a 22" aluminum bolt Easton 2219 and has the flat nocks. Shoots exceptionally well and I've cronographed at 317 fps (which I know is better than they advertise - not sure why though). My query is this: Since I like to play with building my own arrows, is there any issue interchanging the flat nocks with the half-moon style? I'm not really sure I understand why one manufacturer would install the half moons versus the flats (and vice versa). Where I'm at, seems the supply of flat nocks is not so abundant as being able to get the half-moon type so I'll have to order online once I get some advice from all you experts out there! Thanks in advance, Jerry

It's my understanding it has to do with the trigger/string claw that holds the string. If it drops down into the trigger assembly you use a moon nock. If the claw releases upward you use a flat nock.

Using the incorrect nock will invite possible skating of the string over top of the arrow causing a partial dryfire. The kind of dryfire you have no protection from.

Your best bet is to follow the manufacturer's instructions for your crossbow.

I'm new to xbows but I do know it has to do with downward pressure of the string. if your xbow has too much down pressure it will kick under the nock. I would NOT use flat nocks on a bow that recommends moon nocks. the excals will shoot a flat nock. Most bows require moons.

no way would my parker shoot flat nocks. it has a lot of down pressure on the barrel!
