I would suggest the 7-08 over the .243. To each his own, but I've lost several good deer with the .243, and had problems shooting all the way thru them.
I stuggled last year on buying a rifle for my wife. I found that bullet quality has improved substantially in the past few years, and that a .243 would be quite sufficient. However, not everywhere carries those bullets, but most placed carry 7-08 in 140gr. I bought a new Marlin bolt action, owned by remington now. Looks like a 700, with an accutrigger. It shoots lights out, and she dropped one at 155yds last year.
There isnt much difference in the 270, and 25-06 recoil wise, but remington makes the low recoil cartridges for both. If you went 25-06, I would go with the Hornady Light Magnums, and shoot the 117gr btsp.
