The .300 WSM and .300 WM are both adequate.

Anything the 338 will do, the 300 Win Mag will do just as well and is by far the most common and easiest to find ammo for. The 300 WSM will handle anything in North America but is not quite as versitils as the 300 WM.

I would go with a .340 Wby. Mag., or .338 Win. Mag. Good luck.

For large, dangerous game I'd go with the .338. I'd want those heavy bullets.

The .338 is perfect for about everything,Shoot the 250's on Grizz,and 210's Elk and moose,and 200 BT' s for deer and antelope,or be like me and shoot 210's for everything and not worry if you find a grizz antelope hunting.

I have a 300WM and its very versatile. But I still want to purchase a .338 to have for really big game. Maybe even something bigger than that like the .375 or something. DOesn't hurt to have something really large.

The only real answer to this question is an ageless wonder. The 375 H&H. It's a bit much on deer but it can be loaded down. I think it would truly do all you'd ever ask.

Take the 300wm[&:]

Because you mentioned grizzly bear, I would go with the .338. If you already owned a 300WM or a 300 WSM, you would still be fine, but because you are in the fun positin of deciding and shopping around, I'd buy the .338. Even if grizzly was not in the equation, I personally would prefer the .338 for elk and moose as well. Good Luck!

arnt grizzles illegal to hunt?? i dont have bear down here but i would LOVE to get me a grizzle. I was offered a black bear hunt for 3k but not gonna waste my money on a small black bear. I want the real deal.
