Oh, yeah, I know- I was just responding to your statements regarding the seeming dismissal of KE transfer.

Didn't mean to infer that you were singling out anyone in particular.

I also agree with you when you said-

Your opinion agrees with what I've read elsewhere, namely on page 69 of "Quantitative Ammunition Selection"-

Quote:
"When an expanding projectile design is driven at a velocity that exceeds its capacity to sustain the deformation produced by the corresponding increase in hydraulic forces, radical expansion may cause the projectile to lose significant mass through excessive fragmentation. A loss of just ten percent of a projectile’s initial mass in conjunction with an inordinate increase in its frontal area (radical expansion), can result in a significant reduction of the projectile’s terminal penetration and permanent wound cavity mass."
