22 ?

[tr6r]

is it ok to shoot 22lr out of a 22 magnum

They would be awful loose, but they would go bang.
Accuracy should stink.

The other answer would be no... They are two different sizes... The 22 mag is larger then the 22 s,l,lr. It will go bang but you will be streaching the case and the bullet will not be hitting the riffling untill it has exited the case. The manufacturers do not recomend shooting anything but 22 mag out of a 22 mag gun. :)

I have never thought about it, but my first reaction is: Don't do it!

I guess it would depend on WHAT firearm it is. A semi probably won't feed LR from a Mag magazine and the bolt almost certainly wouldn't cycle (not enough oomph to overcome the bolt's mass).

A bolt wouldn't give you those issues BUT on ANY firearm you will eventually erode the chamber by firing a shorter cartridge than it was designed for.

Example:

It's hard to find an old (1900-1930's vintage) .22 pump that doesn't have the chamber somewhat damaged by shooting .22 Shorts in it. A lot were used as Gallery Guns and the carnivals, etc used .22S due to cost and low power/safety. Even though the guns were designed for S/L/LR, prolonged firing of Shorts "cut" the chamber slightly (at best) due to the "explosion" happening further back in the chamber than would occur on a L/LR round. Eventually, a L/LR won't chamber or shoot worth a damn if it does chamber.

Just some random ramblings from a guy who spent all day at work, so sorry if this is confusing...:rolleyes:

EDIT: Ah, I see Jericho types faster than I do....but he don't use as many, or such fancy words like I do's!:p

NO! Never put any ammo in a firearm that it was not specifically designed for.

Actually from what I have read the blow back preasure of a 22 mag and a 22 lr are the same, or close enough that it is not a problem. But the wear on the chamber area will be increased and if I remember correctly the 22 mag is .222 or .223 and the 22 lr is .22... Yes the long rifle will probably expand to fit the chamber but it is just not worth the damage or potential danger...

I hadn't heard that. Neat bit of info...

EDIT: Copied to Rimfire Discussions in Rimfire World to get more eyes on this.:up:

I've heard that the blowback pressure for the .22magnum is greater. First heard this in an article about the new Ruger 10/22 Magnum. They had to increase the bolt mass and redesign the receiver to account for this.
As a practical matter, everytime you increase a cartridges bullet mass or it's powder charge, you should see an increase in blowback force, necessitating a bigger bolt in a simple blowback gun.

Don't do it.

From another site (when I asked the same question)

".22LR case Dia. == .226
.22WMR =======.242

If that LR case splits open when fired from a WMR chamber......"

Correction..
The 22 mag is actuall .222 and the 22 lr is .217... Now they have a +/- .002 variance in barrel size... That means that you can get a 22 mag that is .224 in size and a 22lr would be all over the place... If you have a gun that is chambered for both they have taken the time to make sure that the barrel is the right size for both rounds (or atleast close enough to not do damage)
