RE: .300 mag..is it powerful enough for elk??
I remember reading a magazine article years ago, when someone was first using a .338 WM or maybe a .340 wthby on elk. There was a shot the writer took at an Elk that was running directly away from him that he was successful with. I shoot single shot rifles only, so I disipline myself when I am shooting. In that context many cartridges far less powerful than the .300 mag work very well. I use a 7 mm RM myself, but friends use typical .270 or 30-06's for Elk and if they don't come home with one it has nothing to do with caliber. On the other hand, I don't think any of us has ever shot at the rear end of an Elk running away from us.
