vhunter,
Welcome.
I tend to be somewhat of an "accuracy" freak myself, but I need to know at what expense (not just money wise). Specifically, do you mind if the gun is big and heavy?
Let's first keep in mind two things. First of all, the .223 is generally an accurate cartidge. This is not to say ALL .223 rifles will shoot 1/2" groups, but I have never seen a .223 that shot above 1" at 100 yards. Second, it would be incorrect to say that one type of gun will definately be more accurate than another type. A thin barreled gun may be more accurate than a bull-barreled gun.
If you will not be doing too much walking, and you don't mind big heavier-than-average rifles, then I would first recommend the Remington VS SF (Varmint Synthetic, Stainless Fluted). The SF is 1/2 a pound lighter than the regular VS version and it also has stainless steel. I have a VS SF in .308 it shoot close to 1/2" groups with some factory loads.
My second recommendation, believe it or not, would be a Savage FVSS in .223 (which I myself am considering purchasing). It is much less expensive than the Remington VS SF, but generally shoots just as accurate as the VS SF.
Of course, on any factory gun that you buy, you will need to have a trigger job, or install an after market trigger. A competent gunsmith can adjust the trigger on a Remington for about $50. However, I think that some people say that Savage triggers should just be replaced with Tiney triggers (but if you do this, then you might as well spend the extra money and get the Remington VS SF).
Now, if you really want the BEST trigger on the market, then you have to get a Jewell trigger. I have one on a Remington BDL SS DM and NO WORDS CAN ACCURATELY DESCRIBE THE QUALITY, FEEL, AND FUNCTION OF A JEWELL TRIGGER. :grin: Be forewarned, they are expensive - around $230 without installation (which should be by a competent gunsmith).
If you get you get a trigger job, then the trigger pull can't, or at least shouldn't, be less than 3 lbs, or maybe even 2 3/4 lbs. However, some Jewell Triggers are 2 OZ (I said OUNCES). This, I believe, is waaaayyyy to light for hunting. These are just for benchrest competition, but you can get these triggers for 1, 1.5, 2.0 lb pull, etc.
