.22LR in .22Mag?

It will fire, but the case will expand incorrectly and probably split. It's not something that you should do, and it probably will cause a failure to eject in a semi auto. It probably won't hurt the rifle if you want to try it, although you may get a face full of gas.
 
It has to do with diameter. The .22 lr uses a heeled bullet so it has a smaller case diameter (.226") than the .22 mag (.242") so as mentioned above it may cause the case to rupture damaging the gun and the shooter.

You are correct about the different size case dementions,and the 22lr healed
bullet is .222 and the 22 mag .224. The healed 222 will swell and fit the

groves of the .224 barrel. I have an old H&R mod 676 that has a non recessed

cyl in 22 mag ,and will shoot cb,shorts,lR,22WRF,and 22 mags !

The swelling of the shorts longs or any of them come out with just a

push of the ejector rod.

This is a revolver and you cannot do this in an auto or rifle that the

chamber is cut for the 22 mag as the chamber will be too deep and the

firing pin will not hit the case.

But if you can find a non reccessed 22 mag cyl revolver ,then you have the

SHTF pistol because it can fire any 22 cal rounds you can find!

1. No
2. Data stamp, the thing on the side of the barrel. Don't ever deviate from that unless you have a couple of spare eyes or finger tips laying around. Taking on a "tinkerers" mindset with loads is a very dangerous way to conduct yourself in my opinion. Yes, better to ask than not too....but you can't blame internet advice when you're in emergency w/o an important body part altered..or gone...or worse.
 
.22lr will fire in a Magnum chamber. The case may blow out to fit without splitting the body or the rim. If it does, there will be a release of high pressure gas. Its your face and eyes behind the gun.
Yes, it can be done. Maybe in a case of extreme necessity it might be an option. But it is not a good practice.
 
Guys....all due respect, but I'd urge you not to encourage unsafe practices. Explaining the "how", followed by a "maybe not a good idea" is too mixed a message in my opinion.

S1de8urnz~any time you choose to ignore the data stamp on your barrel (the info. stamped on your barrel by the manufacturer telling you what ammo to use) you're taking a HUGE risk with your safety.

With all due respect to you also I talked about a non recessed cyl in a

22mag revolver(which i think would handle the pressures of the 22LR) as

the cyl is NON RECESSED the shell lays flat out and will fire every time.

There will be no more blow back than any other 22 round ,maybe less

because the swelling of the case will stop that.

That is a an overly broad generalization. There are many examples of safe cartridge/firearm combinations that may not be so marked. Any straight-walled, rimmed case can be safely used in a chamber meant for a longer, but otherwise identical case. For example:

-.22 S/L/LR in .22LR
-.22 WRF in .22 Magnum
-.38 Special in .357 Magnum
-.44 Russian or .44Special in .44 Magnum

An explanation as to why a given combination is unsuitable and what can go wrong is more likely to be taken seriously than a blanket "don't do it".
 
Thanx tjhaile. Thats what i was getting at. The explenations are great and thats all I really wanted. I didn't really plan on trying it and figured it had more to do with just general performance of the rifle shooting a smaller round.

But a 22LR in a chamber for 22WRF and 22W Mag are not this . The 22LR is a smaller dia. case and rim and this is what has been stated.

it will work-but you will get abnormal leading at the chamber/barrel junction due to the shorter length-I'd stick to the .22 mag-add @ 25 yards to your range
 
Do not even try it. only use the ammo that is designated by the barrel stampings. Many different cals can fit different chambers, but these are much closer in specs than a .22 Winchester Rim Fire and a .22 winchester magnum.
