I get it that some guys bash magnums. I currently own a 300 RUM, 300 Win mag, 7mm weatherby and a 375 H&H. But in also own and hunt with a 25-06, 280, 7mm-08, 308 and a 30-06.
The problem I have is guys saying the performance is the same between magnums and standards. It's not, and never has been. Higher velocity changes the way bullets perform, and it destroys more tissue. The wound from a 7mm-08 does not look like the wound from a 300 rum, etc. I think we can all agree on that point. As such it's not a stretch to then admit that given the fact the animals succumb to a loss of blood pressure and organ damage is what causes said loss, that a magnum does indeed kill more abruptly in many cases. The caveat being that projectiles are similar etc.
