Well?
me said:Why can't anyone check for themselves on this one?
.22LR/L/S and .22wmr/wrf are entirely different families of ammunition, in fact, they are not designed to be compatible because at one point they were competing for the rimfire market.
Yes, it is possible to fire a .22LR from the chamber of a .22mag gun, but you risk split casings and shrapnel in the works of your .22mag gun, if not in yourself.
It sort of works with single-shot firearms, because the chamber is sealed and any debris dumps out.
Some revolvers have a conversion cylinder and a bore diameter that works with either round, in response to market demand and the possibility of "close enough" sizing.
Just because ammo says .22 on it does not make it compatible, and attempts to fire the wrong ammunition in a firearm are rarely wise. Considering the low cost of even premium .22wmr ammo (comparable to really cheap centerfire pistol ammo), even someone as cheap and stingy as I am has no need to save by attempting to use .22lr in a .22wmr chambered gun.
The big problem is that ammunition nomenclature is often made confusing on purpose by marketers and manufacturers, in an attempt to associate one caliber with another in the minds of consumers. If the ".22 Winchester Magnum Rimfire" had been properly labeled as ".224WMR", and the ".22LR/L/S" family been designated as ".223", these questions would be far less frequent.
me said:You're missing the point here, this isn't like shoving a .38special into a .357mag chambered gun, it is like shoving a .44mag into a .45lc gun, the rounds aren't from the same parent case.
The rim is wider on a .22mag/wrf round than it is on a .22s/l/lr round.
The cases of the .22mag family are tapered, the .22lr family has straight walls.
The projectiles are different designs and diameters.
Don't get annoyed with me or the others who understand the lineage of the various rimfire loadings, get mad at the jerks who named two different base designs "twenty-two" and expected everyone to figure it out on their own.
someone else said:Darned if the 22mag didn't look just like the 22lr in comparison with the shorts
It wouldn't if you had both in your hands.
me said:The .22mag rim is wider, and the case is fatter at the base and tapers a bit. The .22mag is NOT a souped-up .22LR, it is a souped-up .22WRF, which was designed from the start not to be interchangeable with .22Short/Long/Long Rifle rounds.
The .38spl/.357mag relationship is mirrored in the .22S/L/LR, but the relationship between .22LR and .22mag is more like that between .357magnum and .357sig
me said:Look up .22mag and .22LR on wikipedia, they are very different cartridges, although their required barrel size is close enough.
Heck, put the two rounds next to each other, the differences are obvious to the most casual observer. They do NOT fit in the same chamber, they do not have the same diameter rim, and the bullets are mounted in the cases in different ways.
A conversion cylinder will let you use the same bore for both, shoving one into the wrong chamber will put you in risky territory, even though bubbas abound who have managed to cram a .22S/L/LR boolit into a .22WMR/WRF gun.
