Bowtech recommends the moon style...!
Changing them (out?), seems to be a waste of effort. If you want flat nocks, just buy "arrows", WITH flat nocks to begin with!
I shoot moon in my Stryker...shoots great.
I shoot moon in my Darton Impact, works great.
I shoot both moon or flat in my Fireforce and Stinger (Darton) "both" work great.
I shoot both on an old Barnett, works great.
I shoot both in a newer Barnett, works great.
And...I shoot flat only on my Wyvern Medieval bow, works great.
I see no difference in accuracy.

NOW ... what to do with my remaining 22 plastic moon nocked arrows?
Question ... the nocks appear to be super glued in so am I correct in saying the only way to salvage the arrows is to cut the nocks off thereby shortening the back of the arrow 3/8" or so?

Are you sure you did not break the nock while shooting a group. Most problems with nocks result from one arrow hitting another in the target. Almost like a "robin hood". It's when you don't catch it, the next shot with the arrow that has been damaged can cause some trouble.
After about nine Robin Hoods and a bushel of ruined arrows with my verticals at my standard practicing distance of 30 yards; I'm reluctant to even shoot more than two arrows at a spot with my vertical. In the beginning it's exciting to see one arrow sticking into another ... after a few you just start to see dollar signs growing wings. After that ... you just get a sick feeling in your stomach when you hear one arrow slap another.
So ... I'm 100% sure it's not a semi-Robin Hood or injured arrow. I have never shot two crossbow arrows at the same spot. I've had high expectations for accuracy right from the beginning; and I’m shooting 18 yards indoors ... so I knew "groups" would amount to destroying all two dozen of my arrows within a few weeks. I rotate shooting 9 arrows off sand bags at the 9 spots around my 450fps Spyder target; then go record the distance from POA of each numbered arrow; then pull them and shoot the next 9. I'm looking to become acquainted with, and accustomed to the weapon before I entertain outdoors and longer ranges. I have also incorporated a quest to find the best arrows out of the batch I have. Theoretically, that makes about 12 shots on that arrow before the nock split. Of course it “could” have been my error; but as I said, I seat each arrow firmly and give it a slight twist to make sure it’s in the bottom of the nock; and I don’t see what I could have done wrong to split the nock in half. I did a fair amount of research before purchasing the Strykeforce and was well aware off the hazards and causes of a dry fire. Being a rookie to the crossbow, I’ve been focused & vigilant in the arrow loading area to avoid this issue.
Anyway ... I’m learning lessons fast. LOL My reluctance to slow down my arrow with the oft recommended “heavy” aluminum nocks just cost me a string, an unknown amount of downtime until I find someone to press this contraption here in NJ where crossbows were legalized about 15 minutes ago, and down time to get these plastic nocks off this brutally fast and powerful Strykeforce. Funny when you’re new to something you read reams of information and so much is lost to you because you have no reference points to gage importance.
A question ... it appears that the string rides extremely close to the rails and at 185lbs DW that string can't be going too far from a dead straight line during the shot. I can see no way for it to slip OVER a flat nock. On the other hand ... this moon nock deal requires a test to "FEEL" if it's seated correctly on each loading. It's not like a vertical where you can see that everything is right and proper. Taking this one step further; why use moon nocks at all? Where's the logic? Indexing for arrow spine would make some sense but that's way beyond anything the factory would be concerned with.

Many carbon arrow manufacturers have flat plugs (albiet, plastic) to replace moon nocks and many of them will also fit other brands/models.
An enterprising shop with CNC lathes could crank plugs out by the thousands to remedy this engineering deficit!
Don't give up on removing the old moon nock... some of them are push-fit and not glued!

Now ... I had one speed nock loosen and move on my string and there's some speculation that it might have caused space alien like harmonic waves that knocked the snot out of da plastic nocks. I don't know harmonics, from ebonics but I caught the loose speed nock after about 30 shots and used my nock crimper to tighten it back on. So if that IS the case it means those arrows were likely beaten up after less than 3 shots each. Worst case scenario, even if my crimp job had the nocks misaligned or out of synchronization or "whatever" the damage took only 12 shots each arrow. While this tiny speed nock's demonism is beyond my capability to comprehend and extrapolate into chaos & mayhem on my arrows ... it might be a good idea to keep an eye on the “Speed Nocks” on your Strykeforce string just in case you embrace that they’re at the base of this case.
On another front ... I had purchased an extra string with my bow so I was ready after the “incident.” A few calls to local bow shops to press the bow was met with “We don’t work on those things.” Soooo ... I built a home made press out of some scrap tubing I butchered out of an old lifting jig I had laying around. While the simple model took hours to build, it functioned flawlessly and had the string changed in 60 seconds. Now I’m ready for my next adventure in Strykeforce maintenance.
THANK YOU to those who were generous enough to share your ideas with photos for home made presses!
