Ballistically speaking its pretty much the same as the .300 Win Mag, and that is definately enough gun for the animals you have mentioned. Would agree with the 180 grainer previous recommendation. The only noteable difference, affecting this cartridge, betweenthe WSM and WinMagis the case length. The .300 Win Mag can handle longer bullets than you will want to stuff in your 300WSM, otherwise it will work about the same. You stuff to long a bullet into the WSM, and you will start losing case capacity.
