I'm going to toss this out for discussion sake and I have not done (as of yet) any deep research on the .22 WMR round. When did Winchester develop the WMR round? Were .22 handgun cylinders "weaker" back then or were the cylinders shorter? I wonder why Winchester didn't just extend the length of the .22 LR, just like the .357 mag? I just pulled out my Ruger New Model Single Six and both cylinders are the same length, and there is plenty of room in the non magnum cylinder to have a .22 ELR/MLR chamber (Extra Long Rifle/Magnum Long Rifle - if there were such a cartridge). Why make a longer and larger diameter cartridge? I would suspect that back then the extra powder in an extended LR cartridge probably wouldn't be as powerful as Winchester wanted.
By the way, this is a great topic to discuss probably the most used cartridge(s) around. It fits right in with a rifle I just repaired this week, A Springfield J. Stevens Model 87A rifle (no serial number) It is marked .22 SHORT LONG OR LONG RIFLE ONLY AS AUTOMATIC. Got it working for the customer and the .22 LR's cycled fine. Didn't have any Shorts or Longs to test. Guess I should get some to have for testing purposes.

My understanding is that the greater velocity of the wmr made the engineers want it to be capable of being traditionally lubed over the simple wax tumble lubes used in the 22lr back then

I have never pulled a bullet from a WMR. |

I've watched this thread with extreme interest. Knowledgeable members posting with the same experiences I've had.
I just measured 4 different 22 LR Bullets:
CCI Velocitor .2245"
CCI Stinger .2235"
CCI Mini Mag .2245"
CCI Clean PC .224"
I've posted many times I've gotten the best accuracy from Velocitors. Is it because of the diameter? I suspect so, but can't prove that.
I've found accuracy to be best when the relationship between everything involved in working together instead of a single part.
My FA97 is my most accurate rimfire revolver, no surprises.
The throats on both cylinders are .2225". Since I've never measured any 22 Rimfire Bullet smaller than that, I know all Bullets are sized down as they pass thru the cylinder throats.
Leaves me curious to the barrel groove diameter. I'll assume .222", but haven't verified it.
It would fit as Bullets would be .0005" oversized as they enter the barrel.
I did slug the barrel of my Ruger S6 Hunter at .2237" and I believe that explains its great accuracy.
Guess I should slug more barrels and gather data...

bigbore,, to do the experiment,, you should get an earlier Ruger Single-Six. One made prior to serial number 150000. Those have a smaller bore diameter.
The .22 Mag was introduced in 1958. An interesting side note here. In 1958,, Ruger put out it's catalog/flyer. The Bearcat is on the cover,, and it says; "Shoots all .22 RF ammo." Well, then Winchester brought out the .22 mag, and Ruger rushed to put out a modified catalog,, showing the Bearcat as shooting; ".22 Short, Long & Long Rifle." Two variations of the 1958 catalog.
