the idea that greater cavitation leads to a smaller wound channel is simply false

Please reread my post:

There are two distinct wound channels, permanent and temporary.

Permanent channel is created by the direct terminal behaviour of the projectile, ie diameter, deformation, fragmentation, yaw, and secondary projectile propagation. temporary wound channel is the direct result of drag and energy transfer to tissue resulting in volume displacement of tissue. The effects of temporary channel formation is tissue type dependent.

So if your projectile has little drag and penetrates deep then by defintion the temporary wound channel is smaller. You cannot challenge that ! I did not infer that the permanenet wound channel is smaller because of less drag.
