Well, only someone as arrogant as yourself jwp would pretend to know
My motives better than myself.

That said, only a wishful thinker would pretend to notice a bigger
Wound channel b/w a 45 colt vs a 44 mag. And it would take more naivety than I could possibly describe to think any difference would matter when killing something.

Bigger and significantly faster may very well produce a significant wound channel especially when dealing with expandables but there I go again using evil words like expandable and velocity.
