Anybody know if Frank Pachmayr did custom conversions on K22s to shoot 22 WMR? Early 1960s?
Thanks!

It's possible, but since the model 48 in .22 MRF came out in the late 1950s (at about the same time the round was introduced) he might not have.
The model 48s actually came out in 1959 before Winchester introduced their first rifle (the model 61). I have 2 1959 model 48s (no-dash). one 6 inch and one 8 3/8 inch.

K22 WMR Conv
Ever see anything like this?
The barrel is original. I am guessing that the forcing cone would be machined down to accept a longer cylinder. If so, It would no longer be possible to use a 22lr cylinder in this frame.
Thoughts?
It appears that the cylinder bores and extractor could be machined for the 22 WMR, without modification to the barrel. Last 2 pics are an unmodified K22 fyi.

Is that GA ODT?

Yes. I bought that K22. Trying to find out some history.
Thanks.
Thanks.
It's still up. There were some talented gunsmiths around here back then, picking up on the popularity of the Model 48. A letter would tell you where it went out of the factory but that might take you down a dead end.

SN dates to 1957. Looks like somebody was too impatient to wait on a Model 48. Word of mouth has it this was done by Pachmayr in the early 1960s.
Wonder what 22lr and 22 WMR ammo cost in 1960?
I think this revolver should be great for small game and snakes on 2 legs.

Have you measured the cylinder to determine it is longer than a normal K-22 cylinder?
22 Magnum fits in a rechambered 22LR cylinder. I have a dual cylinder 2" Model 34

Have not measured the cylinder yet. Just bought the revolver but it is not in my possession yet. I will measure it and post what I find.

The LR and magnum cylinders are the same length. my dad bought the 6 inch that I now have back in 1959. At the same time he bought a 22 LR cylinder and re-cammed it to work in the magnum frame. I believe at one time in the 60s S&W offered the 48 with two cylinders as an extra cost option. I may be wrong on that however.

I have a box of Winchester 22 magnum I bought in 1964, I had a Stevens Favorite re-barreled to 22 magnum. Cost $8.00 including drilling and taping for a scope. The tag on the box says $1.50. I still have it since it was a single shot and I didn't shoot it much. One thing you have to remember, I worked for Fisher Electronics plant in the mountains outside Lewistown, Pa and they paid the princely sum of $1.27 and hour to assemble stereo equipment.

PS I paid $3.50 for the Stevens.

I have 2 Model 48's with the auxiliary 22lr cylinders, 1 from around 1959 for sure, not sure about the date on the other.

Interesting, obviously someone specifically wanted their K-22 converted to MRF and not a model 48.

I once bought a very nice mid-1950's vintage K-22 Masterpiece at a gun show. The barrel and all six chambers appeared dirty but I didn't bother to run a brush and patch down them figuring a lot of people think .22's don't need to be cleaned.
When I got it home and cleaned it I found the barrel and every chamber were severely corroded. Maybe some previous owner fired some old .22 ammo from prior to when it was non corrosive and let it sit ? Anyway, I had done quite a bit of business previously with the seller and he was a standup guy and refunded my money. I often wondered what happened to it.
It was a candidate for rechambering for .22 WMR for sure. Cosmetically it was excellent.

So you had to work (at a technical job) for about an hour to pay for one box of ammo. The rifle with mods cost you about 8 boxes of ammo.
My 22wmr cost $18.00 today at the LGS (12 times your costs). Using this factor, your wage would be $15.24 today. (seems low)
Likewise, the rifle would cost you about $138.00. (also seems low)

I was under the impression that the bore diameters were slightly different the .22 lr. .222 and the .22 wmr was .224, all of the convertible .22's that I recall were from .22 mag to long rifle, including the .22 jet, which had a bore diameter of .222. The accuracy of the .22 lr could be slightly affected in the .22 mag barrel.

Go actually measure some unfired 22lr bullets. I have and have yet to find any that are actually .222, they are all .223 or .224 Plus, although the groove dia of a 22 mag barrel MIGHT be .224 the land dia is usually closer to .218. While you may not get target rifle accuracy, very few people can shoot a 6" revolver well enough to tell any difference.
