Purchased a NO 1 some years ago at a gun show and it was in a battered condition, rough if you will, and had 22/250 barrel installed and re blued the action and barrel and refinished the wood on it as well. Shoots very well with the Douglas barrel and the 80 and 90 grain bullets for the twist is 1 in 8. Shot it a number of times on 600 yard matches w/ scope and actually won a few. Had Douglas make me another barrel chambered in 348 Winchester and only real change other than the barrel was the extractor due to diameter of the 348-case base, can hunt mice to moose with it. Not long after the above rifle was in my hands, found a Ruger NO 3 and had Douglas make me two barrels for it, one being 45/70 and other being 6BR. Had the 45/70 barrel a bit heavier than the factory barrel in that caliber for needed some help with the stout recoil of that caliber and it shoots very well with handloads out to 200 yards, plenty of punch even at that range with 400gr + lead bullets. Now the 6BR is the super accurate one for at 150 yards have shot groups of 1/2" for 5 rounds, super surprised at that performance.
This barrel is stainless steel and on the heavy side and 24" in length and yes, it is heavy but only shoot it from a bench or with a bi pod, not something you would want to carry on a long trek so to speak. Both of these Ruger's have the two screws in the trigger and after some messing with them cannot complain about the triggers at all.
Had the stocks sent to a person that does fine checkering work and really sets off the little NO 3.
Glad Mr. Bill Ruger developed these rifles for they are indeed classics in a current market of plastic and aluminum firearms.
