RE: .300 Weatherby Magnum
Probably the greatest all-around big game cartridge ever invented. It's a bit too much for my bad shoulder, and selling mine hurt as much as loosing your best birddog. None of those other rounds do anything more than the .300 Wby and they kick a whole lot more and burn a bunch more powder. This is the quintessential American cartridge.
Good Dogwork and Good Hunting
