I started out with a 223 Savage 10T-SR from Cabelas. Out of the box, it needs nothing added to it (other than an optic) to get you shooting for $600. I have achieved a 0.7 inch group at 200 yds with it and my skills are not very developed yet. My only complaint is I'm not too fond of the standard pistol grip which strains my wrist shooting off of the bench. I just picked up a new Savage 12 FV in 223 at Cabelas and put it in a Bell and Carlson Medalist stock. I haven't been to the range with it yet but the shooting position feels really good with this stock and I hope it shoots good. I also have a Savage 10 BA Stealth in 223 but I'm not sure I will ever learn to like it off the bags. It's a nice setup but I haven't clicked with it yet.

Good luck with your choice.
