Thing is nobody in this century that I'm aware of has argued that temporary cavity should be emphasized at the expense of adequate penetration, even Dr Courtney held that adequate penetration was more important.One side claimed that temporary cavity was very important and that ammo design should emphasize that even if it resulted in minimal penetration.
The other side claimed that temporary cavity and tissue stretch was never an issue and that penetration with reliable expansion was the only thing that mattered.
The truth is somewhere in the middle, but neither side was inclined to rational discussion or even the hint of compromise.
You have people in the other camp still going in this thread.
