Get a 30/06 Improved and you can hunt both places
Why mess with anything else? The 25/06 and 7/08 are 270 WANNABES
That's EXACTLY the way I see it... unless, of course, you're talking a Kimber 84. Then, all bets are off... sometimes a particular rifle is more important than its chambering... the Kimber 84 Montana is one of those rare rifles.
