I had a 710. Nothing really wrong with it, depends on what you want. Everything said above of a technical nature is true. No open sites, no cutomizability without serious smithing. It's a package gun, nothing else. I'm told that the bolt smoothens with use and lubrication (self lubricating my foot). Mine was $350 and I would never pay more. I sold it to go towards an M1 Garand and a Savage in 300 Ultra Magnum.
All in all, nothing wrong with it, but you may want to see if it's really what you like. I'd second the reccomendation of a Savage. The way I see it, Remington doesn't hold a candle to Savage's accuracy. With Savage you have more options. The main advantage of the Remington 710 is it's ultimate durability, lock stock and barrel. The stock is comfortable too with the Monte Carlo cheekpiece, and the material feels nice, though oily hands will slip on it.
Here's my reccomendation: Check both out, shop around, and get a firm price for each. Then decide what you want. If your conditions are hazardous, go with 710, especially cold weather. If extreme accuracy is what you want, go with Savage, though 710 will probably do fine for hunting.
Savage does offer stainless synthetic models, but they cost more.
By the way, I thought no one could top the 710's stock for ergonomic comfort, at least with my body, then I got my Savage.
