I've never had anyone put a tag on a deer I've shot with my .300 Win Mag.
None have went farther then 5 yards. I can not say this about the 7mm-08, .30-06, .308, .243, 30-30, .35 Remington or other calibers I've had except the .270 Win was as good on deer.
Neither have the two elk my .300 WM has killed or the black bear.
I love to watch the eyes open when I light it up at the range. Kind of a macho, ego thing I guess....
