The configuration you describe is refered to as an AB (A weight barrel and beavertail forearm). This was one of the common rifles produced in the first few years of production, then it was dropped until reappearing again in about 1980. It lasted 4 or 5 years this time and was produced in 223, 243, 270, 7x57 and 30-06. It was resurrected once again a few years ago as a special run for Lipseys in 25-06 (with a 24" barrel), and was cataloged for a short time in 204 Ruger with the typical 22 inch barrel. As far as I know, there were never any in 257 Roberts.
Johm: In case you didn't ask, Ruger will install the correct barrel on it for $396.40.
If the rifle has great wood or is a fairley early 132 or the price is right you could always buy it and send it back to have re-barreled by the factory and have a very nice "correct" rifle at a reasonable price.
Last year I bought a 257Ackley Improved #1 off GunBroker for $505. I confirmed it had shipped as a 257 Roberts "B" and that they still had correct barrels and the price.
After the gun arrived I sent it back to Ruger and had it re-barreled to 257 Roberts for the cost quoted above. This is a early gun that shipped in 1980, the first year that the Bob was offered in the catalog. So it is correct with a warning barrel and a square red pad. This one has lovely red wood.
I then used the perfectly good 257 Ackley Improved barrel and stuck it on a 243 "B" with nice wood but of no particular rarity. The smith charged me $150 to install and head space it to the rifle.
If you aren't interested in the rifle and the price is right I'd sure be interested and appreciate a heads up on a private note.
That the barrel was cut was my best guess. I've never even heard rumors of a 22" "A" 257 Roberts other than the stainless/walnut Lipskey Special. I have also never heard a rumor of anything other than a factory "B" in over 40 years of this game.
Matt: Yes it would. Lipskey is supposedly making a run of "A" rifles in 250-3000. Of course we have been waiting impatiently for almost 3 years for them to appear.
They do still say they are goig to make them but haven't assigned a date yet.
I got tired of waiting on an "A" or "AB" 257 Roberts some years ago and built an "AH" same rifle but with the Alex Henry forearm in 257 Ackley Improved. I chose it over the standard 257 Roberts ONLY because I found a stainless match grade Shilen barrel in the "A" profile, 22" long that had been fluted. I used a 243 "A" as the donor rifle so I didn't have to change the extractor and the rib fir perfectly and sling band just slipped on.
Last year I bought a set of Conetroll rings and a Conetrol base that fit and replaced the rib and factory rings. It didn't save any weight but those Conetrol rings without screws or projection do look cool. It's scoped with a Leupold MKII 2x7 Mini and YES it is a great little rifle and Ruger should make a factory "A", "AB" or "AH" in 250-3000 or 257 Roberts!!
