I have a 12FV in .223 that I strapped to a stock from a 12BVSS. It's really heavy, and REALLY nice. It shoots .5s reliably, and I can't ask it to do any better than that for a dead-stock factory rifle. I would suggest getting into handloading. It's impossible to articulate how important it is until you have done it for yourself. There is no thought in my head about factory ammo any more, only how I can tighten groups, up velocity, or make the most immediate possible kill.
