7mm Mag vs 300 Win Mag for Plains Game

[firstsafari]

I amd in the process of planning my first safari to Zimbabwe and am curious about the preferred caliber for plains game. I intend to hunt Kudu, Gemsbuck and possibly Sable.

I am new to big bore hunting and am trying to weigh the pro's and con's of the 300 win mag. It seems from www.chuckhawks.com that the 7mm Rem Mag would do just fine.

Any suggestions are appreciated.

Thanks,

First Safari
