Burch,
The Mountain Rifle is one of my favorite hunting guns. I've had one in .280 for almost ten years, and have taken quite a few deer with it. In fact, I killed a nice 8pt with the gun this morning! Mine has been accurate with factory ammo, and will average better than 1.5" with just about any load you feed it. Mine is a blued/wood model with hinged floorplate, but I also had a stainless/synthetic one that I recently sold. I wish I had kept it, but I am not much of an '06 fan (heresy, I know). I don't necessarily care for the detachable mag versions, as I think it ruins the graceful lines of the stock.
If you are serious about getting one, let me know. A friend of mine owns a pawn shop, and he has a very nice stainless/synthetic in .270 (with the blind box magazine). It has a Bushnell scope, and is in excellent shape. I could weasel him out of the gun for around $375, so let me know as soon as possible (I don't know how long before he sells it). Email me at the address below, and I will talk with him for you.
