Dry-fire warning
Bolt length, nock type and minimum grain weight are quoted from each manufacturer's published arrow data and owner documentation, cited on every page. A nock or grain-weight mismatch can cause a dry-fire that damages the bow and can injure the shooter. Confirm against your own owner's manual before shooting, and never drop below the stated minimum total grain weight.

The TRX 26 is a 2025 twin-riser TenPoint at 460 fps on a railless Zero-Trac barrel, matched to the 445-grain CenterPunch HPX with an Alpha-Nock HPX. The bolt rides on bearings, so the nock engagement is what keeps it on the string.
On a railless Zero-Trac bow the correct Alpha-Nock HPX is not optional. A flat or Omni nock can let the string slip past the bolt and dry-fire the bow at 460 fps.
