Choosing crossbow bolts
Choose a bolt that matches your crossbow's required length, nock, and total weight.
A bolt that’s too short for your crossbow’s power stroke creates dry-fire risk: the string can catch empty air where the bolt should be.
The short answer
Choose bolts within the model’s specified length and grain range, with a nock and diameter that fit its system.
Bolt length and range
Bolt length has to match the crossbow’s specified range; too short creates dry-fire risk even with a bolt technically loaded.
Nock style and seating
Nock style has to engage the string and cams correctly. A nock that doesn’t seat fully can slip under the string’s initial force.
Rail fit and diameter
Diameter controls fit through the rail and any accessories, such as lighted nocks or certain broadheads; an out-of-spec diameter can bind or wobble in the rail groove.
Grain weight and stored energy
Grain weight is part of the approved projectile mass for that crossbow. Going under the minimum can push stored energy into the limbs and stock instead of the bolt.

Before you buy
Confirm bolt length and weight against the manual, not just the model name.
