7 mag kills stuff dead, but to me it is not as popular as it once was for a few reasons. In no particular order...
1. It has a belt
2. It doesn't do anything a .30/06 or similar can't get done with cheaper ammo and less bluster
3. With laser rangefinders and dial up scopes, a couple of inches extra of drop are meaningless. "Flat shooting" isn't needed as much as precise ranging and come-ups
4. It isn't .30 caliber
