That's the same article I read recently. Makes sense that the slower velocity could make penetration better as opposed to higher velocity. Kind of like an arrow penetrating through game despite of the very low velocity. But there must be at least some advantage to the bigger faster guns. Why else would people use them over a lighter handier rifle? I have a Winchester Model 70 458 Win. and it's a very nice rifle. But damn is it big and bulky! The little lever gun feels much better in my hands.
