I recently bought the "loaded" model which purports to have a match barrel (except with the standard barrel profile- not the medium weight contour of the National Match model), a match trigger and match sights. I went with the carbon steel model just because the price was already so high that I was having trouble breathing! I also figured that rust resistance wasn't quite as advantageous if the entire rifle isn't stainless. There may well be advantages to a stainless barrel in terms of fouling or barrel life, but I would defer to more technically sophisticated members on that.
I really like the match trigger and feel it justifies the extra cost over the standard model.
The walnut stock is very nicely done and very attractive. I'm sure it costs a whole lot more to produce than the fiberglass. I saw used stocks in walnut, birch and fiberglass (with all hardware) advertised at great prices by Forrest, Inc. in the Gun List. No web site, just a telephone number that is almost always busy: 619-561-5800, California time. I ordered a fiberglass stock for $10.95! I'll report back when I get it.
Enjoy! It's a great rifle.
