A timing adjustment assembly for a compound archery bow is provided. The timing adjustment assembly is coupled with a pulley assembly and power cable of the archery bow. The timing adjustment assembly includes an adjustable component and a stationary component. The stationary component is attached to either the pulley assembly, the power cable, or the riser of the archery bow. The adjustable component is configured to move in a linear direction between multiple positional arrangements relative to the stationary component. The movement of the adjustable component changes the effective length of the power cable by moving the termination anchor point of the power cable or deflecting the power cable. The timing adjustment assembly adjusts the effective length of the power cable and relative synchronization of the pulley assembly with the archery bow in a brace position through the change in termination anchor point or deflection.

A pulley assembly for a compound archery bow comprises an axle, a draw cable pulley, and a pair of split-buss let-out pulleys positioned on opposite sides of the draw cable pulley. Each secondary cable of a split-buss end of a power cable is wound in a spiral arrangement around a corresponding split-buss let-out pulley. As the bow is drawn, the pulley assembly rotates, the draw cable pulley lets out a draw cable, and each split-buss let-out pulley lets out the corresponding secondary cable. The spiral arrangement results in lateral movement, away from the draw cable pulley, of a contact point of the corresponding secondary power cable on each split-buss let-out pulley as the bow is drawn. The spiral arrangement can include a corresponding spiral groove on each split-buss let-out pulley.

A pulley assembly for a compound bow comprises a draw cable pulley and a power module attached to the draw cable pulley and adjustable among one or more positions and two orientations. Changing the power module orientation at a given power module position alters the bow's draw force curve and stored energy without altering the bow's draw length or draw weight.

A shock-absorbing bolt for a crossbow comprises a shaft, a forward flange, and a shock-absorbing mechanism coupled to the shaft or the forward flange. The forward flange is coupled to a forward end of the shaft and has a forward surface with a transverse area that is greater than about three times larger than a transverse area of the shaft. A tapered tip can be attached to and protrude from the forward surface of the forward flange. The shock-absorbing mechanism is arranged so that, upon acceleration or deceleration of the bolt, kinetic energy of the bolt is dissipated by viscoelastic, viscous, or frictional forces within the bolt.

A trigger assembly for a crossbow comprises a string retainer and a trigger mechanism. The trigger assembly can further comprise a piston, a safety mechanism, a secondary safety mechanism, a bolt sensor, or a pair of rotating sears. The string retainer can comprise a pair of opposed jaws.

Each bolt of a set has three vanes and a nock with three diametrical transverse grooves; each groove is perpendicular to a corresponding vane. Each bolt is shot at least three times with a crossbow, at least once with each one of the vanes extending downward into the rail slot of a crossbow. After noting the positions on a target for each shot of each bolt, one vane of each bolt is marked so that shooting the set of bolts with the corresponding marked vanes extending downward into the rail slot results in the smallest grouping pattern for the set of bolts.
