Seriously though, the .300 WM is a great caliber. But so is the 7mm STW. I have two 7mm STW's, and numerous other caliber rifles, including .30 calibers, and larger and smaller calibers. I don't own a .300 WM because I haven't found anything the .300 WM can do, that the STW can't do. The only advantage I can see (a slight one at that), is that the .30 caliber has heavier and slightly more bullet choices than the 7mm. Other than that, I think a STW with a healthy dose of slow burning powder and a Berger 180 will effectively kill anything in N America...Including bears.
There's a guy on here who is a gunsmith and huntin guide (he goes by SkyKing) and he recommends the 7mm WSM to all his clients. He, and his customers have taken all sort of big game with the Berger 180's, bears, elk, & moose included.
With all that said, both are great calibers and should do just about anything you want them to do. But with the STW you have to go ahead and prepare yourself for the price of good Nosler brass. It's not cheap, but well-worth the money.
Other than brass cost and availability, all other reloading components will be equally priced.
I will say this, if you don't mind the brass prices for the STW, then you shouldn't be disappointed.
