Have killed one Elk and one Antelope, both with a 300WM Mag and both at approximately the same distance. The Antelope seemed much more impressed with the initial thump, and significantly so in that it almost tore the front third lose.
Much younger at the time, however now I think I could have pulled both off with a .300Savage. Therefore from no actual personal experience I think the .300 Savage an ideal Elk cartridge.
