RE: Help me build a rifle
Krieger is top of the top of the line. There's also Hart, Shilen and few mor that I'm sure I've forgotten, ER SHAW isn't a "match-quality" barrel but there's little wait on a custom order and they're very well priced. I've heard something along the lines of "they shoot better than they have any business shooting," considering their price.
Fight the temptation to go with a heavy barrel and build a "tack-driver" if you're goin' out west with it. It helps but is usually uneeded in a custom hunting gun with a match-grade barrel. You oughta still be able to get under MAO accuracy.
