deer, antelope, go with 270wsm, if you want to add elk go with 7mmwsm with 160gr TSX or 168gr Berger.
both are fine rounds but from personal experience unless your going to shoot the 150gr out of the 270 you could run into some trouble on major bones.

270 Winchester.......Jack had it right
I'd hands down run the 270 WSM, load 165 or if your twisted for it a 175 Matrix, they did very good on elk this year. The bull I took this year I shot a 865 with the 165 Matrix and I was well within it's range!!!!

I have and enjoy shooting a 270 WSM. I have shot the 150 grn Berger's to great effect. I have yet to try the Matrix bullets which I will order shortly and follow the advice of others on the forum. I can tell you I have always questioned why I went with this caliber rather than the 7 WSM, there seems to be far more bullet choices and the BC's are top of the line in 7mm. I guess its a pet for a lot of reloaders much like I prefer the 25-06 and 257 Weatherby.
