It is a well know fact that all game animals have become tougher since the Interweb was invented. You are not a man, nor a hunter if you don't shoot somthing with the word "magnum" in it.
Face facts - the 7 mauser, 7x08, 6.5swede and all other "mild" cartridges will not penetrate, nor kill any game animal in these modern times......
Actually, the movement was well underway in the '60's (maybe before, but that's when I started reading magazines.) "It makes a helluva noise; it packs a helluva wallop."
