I don't see it going anywhere. At least not in my lifetime.

I've never drawn an elk tag yet, but I have loaned my 7mag to 2 hunters to take on their elk hunts. Both of their guides felt they were "undergunned" then when it came down to it, my handloaded 160gr Nosler AccuBonds for the one guy, and 160gr Barnes TSXs for the other, one shot dropped their elk in the tracks. The other guys in their camp had 300 Wins up to 338s, and only one other guy with a bigger gun one shot dropped their elk. This was 2 seperate years, in 2 different states.

I agree with JamesB, its not about who has the biggest/baddest wizzbang magnum, its who can place their bullets.
