My uncle, who is about the elk killingest fellow ive ever met, ended up with a 7 mag as a short notice replacement rifle about 15 years ago. He doesnt handload, but is a diehard Partition fan, so he loaded up on 160 NPT Federal Premium ammo. He found over then next half dozen bulls he shot that it kills them just as dead and just as fast when you put one through the front axle as his 270 did using the 150 Partition.

Lots of guys around where I grew up are hardcore 7 mag fans, why I don't know as the whitetail deer there average about 150# on the hoof, but fact is the 7 is as good a killer as anything when good bullets are steered through the important parts. Ive seen them work well on deer, elk, and hogs using good bullets, and make a huge mess and long tracking job when poor performing bullets were used or shots landed where they shouldn't. Just like everything else on the shelf.
