243, 260, 6.5 credmore are all great choices. Someone mentioned the 25-06 (that's one of my personal favorites)
The 7mm-08 has taken my house by storm.
My wife has a shoulder replacement (artificial/cadaver tissue) and she loves her little browning x-bolt in 7mm-08.
My 13 year old daughter and 12 year old step son both have 7mm-08s.
I resoundingly agree! Once you shoot a 7mm-08 you'll never want to shoot anything else. On the fun scale it's through the roof. On the accuracy scale, it's also through the roof! My 12 year old daughter that weighs 80 pounds can shoot this caliber all day long. And it EASILY matches the big boys (308 and 300 win mag) on bullseye hits at 1000 yards.
