Re: what caliber for long range (700) yards on deer size game
A 7mm rem mag or a 7mm stw will do nicely and ammo is readily available.
Both are good for 1000 yards but work best in the 6 to 800 yard range.
The next step up would be a 300 RUM if you wanted to go bigger but ammo is a little
The 7 mm RUM Is a power house but ammo has been hard to find.
Also if you like short actions , the WSMs are a good choice,
In other words there are lots of good choices for your need.
