N= rounds per minute

If the design were arranged so that a small part of the explosive force of the next round would be utilized to assist in stopping the forward motion of the recoiling parts, the curves would not be quite the same as in fig. 2-30 because there would be some loss in the impulse producing recoil. However except for this small difference, the computations and procedures would be the same as for fig. 2-30. In making the computations for such a design, it would only be necessary to determine in advancc what amount of momentum is to be cancelled by the explosion and then to subtract this momentum from the momentum imparted to the recoiling parts at any instant.
