Dear Folks,
I love the way that the guys who are advocating the .300 Mag start out by saying "the kick isn't TOO bad," or "the kick isn't SO bad," or "once you sighted it in you will never FEEL the KICK again."
The .300 Winchester Mag kicks, and it kicks like heck. It is a ridiculously high overkill for whitetail deer, mule deer, and black bear as well. Put a 180 grain .308 Wincheser Silvertip into the torso of any black bear and it is going down and going down hard.
Now, I realize that there are some guys who are not bothered by recoil, but that isn't the same as saying that a rifle cartridge doesn't have bad recoil. Look a the charts for free recoil energy. I guessing that the .308 Winchester is somewhere around 18 foot pounds of recoil, and that the .300 Winchester Mag is about what, 32 foot pounds of recoil? Double the recoil? Deafening sound. High priced ammo. And for what? An effective killing range of an extra 75 yards or so?
If you live out West, and routinely take shots at over 300 yards, and are built pretty hefty and can soak up that recoil, and you can actually shoot a magnum without flinching, and you practice enough so that you can easily and consistently hit a pie plate from a sitting position with the magnum at over 350 yards, then I would definitely say that the .300 Winchester Mag is the ticket for you. (Not one in 50 hunters can do this.) If you don't meet any of the foregoing, then it is not. For the most experienced hunters, the .308 Winchester is more versatile and more efficient than the .300 Winchester Mag. You just shoot your game at 250 to 300 yards, instead of 300 to 375 yards. It is that simple.
For those who always yell Magnum when the subject of the terrifying black bear comes up, then I guess it is simply astounding that all of the hunters in the lower 48 weren't mauled to death before the .300 Mag was invented in the late 1950s (or was it the early 1960s?). Gosh, how did our grandfathers ever survive in those dangerous woods of the 1940s.
