Out of the bolt rifles I've shot with, the R700 action is my favorite. Savage would be my second choice. I built a 1/4 MOA 700 in 308 on the stock 18" barrel, and loved it. Barrels can be changed, but all the action is in the action, in my opinion. Everything feels tight, smooth, and intentional. Too many bolt rifles seem to have sloppy bolts, with lots of movement. Sorta like comparing a Remington 870 to a Mossberg 500, the 870 is tight and fluid while the 500 feels like granddads chinky slapstick. I suggest you go to a store and handle them, see what feel right for you.
Accuracy is rather irrelevant to me when buying a base bolt rifle. They can all be made accurate, modified, and most people do anyway. I feel like the R700 is more expensive to build, although I enjoy the simple and effective design of the 700 action and bolt.
