Graybeard,
I just saw this thread after posting a few comments about your next FA acquisition on that thread. My experience with Single-Sixes is pretty broad and lengthy. I've owned at least one continuously since 1963, and usually 2 of them for much of that time, for a total of 5. I've tested and shot many others. I successfully campaigned a stainless 9 1/2" version hard in IHMSA silhouette for a dozen years or more, into the early to mid 90's. I've fired it competitively many, many thousands of rounds... I'd hate to try to quantify a number. It was superb, when compared to the Colt, Smith, and DW competition. It will never be for sale. BUT...it is not the equivalent of a FA 252/83 or 97. I own an example of each.
I would highly recommend that you consider getting a 97 in .22 LR. I would also recommend that it be furnished with Sporting Chambers, not the optional "Match" cylinder, for convenience sake. The very tiny difference in pure mechanical accuracy is more than offset by the nuisance of the match chambers in my opinion.
Trigger and action work on a Ruger single action is easy. I've done my own for over 30 years, and I daresay hundreds of people can do an excellent job. A handful of people could make cylinders and change barrels to make a .22 LR sing. My own personal view is that the expense of making one equal an over the counter 97 (or the much larger 83) doesn't make any sense, unless there is a powerful emotional attachment to that particular Ruger.
Tell Bob to send it on !!
