.22 in .22mag ?

I just inherited a Charter Arms .22 mag revolver, seems to be a nice little piece. Never had a .22 magnum before. I know there are several makers that
sell revolvers with two cylinders so that .22lr @ .22wrm can be fired with the
same barrel, BUT, what happens if you fire .22 lr out of the .22 mag cylinder?

I KNOW you can't got the other way, ie 22mag in a 22lr cylinder, but have never seen it addressed as to what would/could happen firing .22 lr in a .22 mag. Any real experience out there?

The case would not be properly supported. If it did fire the case would split and the bullet night strike the frame. Contact the manufacturer. They may be able to sell you a .22 lr cylinder.

In addition to the case splitting, the bullet might get stuck in the barrel. (Don't ask me how I know. )

That's true. It just might.

The difference is that the 22 is an outside lubricated bullet, held in the case by the heel, where the 22 mag is a jacketed bullet. Thus the 22 case is .223/224, and the 22 mag case is .239/240.

That is the reason .22s often split in 22mag chambers.

The other posts explain the result.

I know someone who shot several .22 LRs in a magnum revolver by mistake. Thought it was a .22 LR. Was stunned by the split cases. Fortunately there was no other damage. Very lucky indeed.

.22 Magnum

Have a couple of .22s with extra Mag cylinders, very impressive and I like them.
Also posess a Ruger 10/22 in .22 Mag with a big rifle scope. It is quite accurate for my use and I absolutely love it but the ammo has gotten so danged expensive! I finally ordered some S&B (Sellier & Bellot) from one or the other ammo and gun places for a more reasonable ammo from Belgium or thereabouts.
I think about 2/3s the cost but regular jacketed, not hollow point. It shoots good, hope you may find some.

At one time Charter sold the Pathfinder Convertible with both LR and WMR cylinders. Numrich has cylinders.
http://www.e-gunparts.com/product.as...ductSKU=319870

Left as an exercise for the class is whether the LR replacement cylinder is the same as the LR cylinder used in conversions and if it is, how much fitting is required to get it to work.

My neighbor the gunsmith came into a Colt SA .22 Magnum and, wanting to shoot it cheaply without splitting cases, found that he could make adapters by cutting the heads off of fired .22 WMR cases and using them to sleeve the chambers. I don't know how well it really worked, he was not a serious pistol shooter and did not keep the gun long.

You can buy such adapters at
http://www.mcace.com/adapters.htm
but you'd have to get two sets of three at $20 each and I don't know how well they would work in a revolver instead of a rifle.

And you _can_ fire .22 WRF in a .22 WMRF. Sort of like a .38 in a .357. The Magnum was just a lengthened WRF. That used to be interesting but pointless but now at least two makers are producing .22 WRF again. I just bought a box from CCI. More expensive than .22 LR but still cheaper than the Magnum stuff. And more appropriate for some shooting situations. 45 grain bullet.

Yes ,it works very well specially with jacketed 22lr `cause it`s much easy to put it in a 22wmr case ,All you need is a metal saw,oil or WD-40 and a little hammer(hit only the headless case !)

How is accuracy firing .22 LR with the adapters?
