I’m just over 400fps and shoot the TP – Center Punch Alpha-Nock Premium Carbon with a fixed DRT head. I’ve punched double front shoulders and BLOW through. Head shot a coyote and it came out mid back. NEVER had one blow up or break other than 1 that exited and crunched into a rock (about the size of a truck). I have a discharge bolt that has been shot well over 100 times. no issues.
Does your CB require the alph-nocks? Are you using after market luminoks?? Just a heads up on that. I had issues with my original bolts and cork-screwing when I replaced the original nock with luminoks. Had a heck of a time figuring that out. Sales Manager for Ten piont explained to me he had the same issue. Its the 1/8″ “slap” when the string drives the nock into the on position. Since, I’ve stayed with the fixed Alpha nocks and this has been a tack driver. Additionally, with the lessor grade carbon bolts, any significant scratch in them was a recipe to break. Because of the cork-screw flight, I had a lot in my targets on a slight angle and they would get hit.
