I have a Ruger 10/22 with a duracoated stainless 20" bull barrel with a match chamber, and it hits a dime at 50 yards all day long. When the barrel gets hot, the group will loosen up. Also when it's perfectly clean it's on a nickle, so it shoots better a little dirty. The rifle cost about the same as the barrel, and I put a Hogue over-molded stock on it. This stock works really well to help tighten up your groups, and gives the rifle an adult-feel, unlike the standard 10/22 which feels short. Volquartsen hammer and extractor. End result is a decent tack-driver for under $1000. Just make sure you're not using standard ammo, a good match chamber should grab those rounds way too tight.
Oh, and there's a tonne of aftermarket parts available for this.
