I would definately stay away from the Remington 710 as the others have said. I shot one back in the summer and it shot decent enough to kill a deer, but it looks and more importantly feels cheap.

As for the Mossberg, I can't comment as I have only seen them in passing at the local WalMart.

Now for the Savage. I just purchased a Model 16(stainless + synthetic stock) Savage in 270 WSM. If you get a Savage make sure you get the accu-trigger. It is by far and away the best factory trigger I have. I am pleased with the look and feel of the gun and I think it will be a good shooter. As was stated in a previous thread, you will definately need/want to upgrade the scope that comes with the Savage.
