ABSTRACT:
An archery bow having a primary energy storage device with a propelling bowstring attached thereto and a secondary and weaker energy storage device including bow limbs having a draw bowstring attached at opposite ends. The draw bowstring and the propelling bowstring are in draw force communication between a predetermined position on the propelling bowstring and the draw bowstring whereby force is applied to the propelling bowstring only at that predetermined position. The tension in opposite ends of the propelling bowstring and the force in opposite ends of the primary energy storage means is equalized and when released propels the arrow in a reproducible fashion without wobble or porpoising.
