Choosing crossbow bolts

Swap in a bolt that’s too short for your crossbow’s power stroke and you’ve created dry-fire risk — the string can catch empty air where the bolt should be.

The short answer

A bolt is built for one crossbow system, not arrows in general

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.

What the listings actually show

The current catalog includes 254 crossbow bolts from 22 brands. Nearly every listing states approved bolt length, nock, diameter, and grain.

Before you buy

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