A compound archery bow has a top cam which is larger than a bottom cam so that the nock point travel between an at-rest position and a fully-drawn position follows substantially a straight line. The nock point on the bowstring positions an arrow substantially perpendicular to the bowstring in the at-rest position. Since the nock point follows a straight line collinear with the arrow center line and perpendicular to the bowstring in the at-rest position, the arrow is released without nonlinear torque or movement of the nock end as it is pushed forward by the bowstring.
