Can a .22LR be shot thru a .22 magnum rifle?

I am new to shooting, i've just got my firearms licence (in Australia) and I know a .22 short can be shot thru a .22 LR. Can a .22 LR be shot thru a .22 Magnum, General logic says it can be done. Any help Much appreciated.

It can be done BUT it should NOT be done. It is not like shooting 22 shorts out of a 22LR chamber. There are a few guns that you would not even want to do that mix, if you can avoid it.

So it can be done but shouldn't be done, why is it different to the 22 short/22LR scenario, in theory wouldn't a 22LR be called a 22 magnum short?

the cartriges themselves are different diameters as well as lenths

the 22lr cartridge will more than likely split in the magnum chamber and thus bad things could happen... most likey wont but could.

22 mag is slightly larger in diameter than the 22lr.

it is really stupid that way back when they messed up these two and did not make them like the 38/357 and 44spec and 44mag.

Blume, I'm assuming you mean the cartridge size, yeah? I'll go measure one in the morning. But we'd only be talking thousandths of an inch, so I couldn't see a 22lr cartridge "exploding" in the chamber of a magnum.

don't fire 22lR out of a 22mag chamber. you'll split cases and possibly get hot gases blowing past the cartridge and back at you. the danger isn't as bad as with high pressure centerfires but it is still a poor decision.

don't do it.

The .22 WMR case dimensions are entirely different from the .22 short/long/long rifle cartridges, whose differences are primarily case length.

The .22 WMR has a significant taper to the case and does not use a "heeled" bullet as does the .22s/l/lr cartridges. If you try to chamber a .22 WMR in a .22 long rifle chamber you will quickly notice the difference. Not a good fit at all. Notice the large difference between the base and rim diameters.

.22LR vs .22WMR
.223 bullet dia .224
.225 neck dia .240
.225 base dia .241
.275 rim dia .291
.040 rim thick .046
.590 case length 1.052
.985 total length 1.350

Just because it has been done doesn't entitle it to be any kind of logic, General or otherwise.
General foolisness is a better title for knowingly doing it.
Ignorance is the most common title for doing it.

done it

i have fired the 22lr in a savage 24, 22wmr. case splits, bullet departs without any authority. i can't remember what kind of accuracy i got. you would probably get more energy from throwing the round at your target.

As stated, this is bad logic.

.... and a bad idea.

It is not a dumb question. Asking before trying it is a good idea.

But, assuming ANYTHING about interchanging different firearms and cartridges is likely to result in severe injury, or death.

Short answer, "No." The reason Ruger's Single Six convertible has two cylinders, one for .22Mag and one for .22LR, is because the cases have slightly different diameters even though the bullets themselves are pretty close (the .22 Mag bullet is also slightly larger, which is why many Single Sixes shoot the .22 Mag a bit more accurately).

That said, I have heard (but never tested) that one can cut the base off of fired .22 Mag cases and slip a .22LR round inside the resulting cylinder, place the whole thing into the .22 Mag chamber, and fire it without splitting the .22 LR case. As I said, this is hear-say only; I've never tried it. Nor do I plan to. Sounds like a lot of work to launch a .22LR in an inefficient way.

Thats great info guys. I've been looking for a new gun and been looking in the direction of a .22 for cost savings. When i saw a 22 mag I thought "Great i can shoot cheep .22lr and get a little more power from a .22 mag when i want." thinking it was the same as the 38/357 but i have learned somthing today.

Thanks.

Speedy

Combat Handguns - .22 WMR "crazed addict attacks granny"

There was an interesting little article about an elderly woman who fended off an attack with a North American Arms .22 mag mini-revolver. One shot (fired through her handbag) and the guy was down.

That's good news. My 1911 in .45 Auto is feeling awfully heavy in this hot weather. I guess I can trade it in on a .22 Mag mini-revolver and still get one-shot stops.

I'm so relieved.

Absolutely not! Not trying to be mean, but ALWAYS shoot the kind of bullet the gun is made for. The only to bullets that are interchangable (that i know of) is .223/.556x45mm NATO and the .308/7.62x51mm NATO, oh and you can shoot a .38 special in a .357 magnum, but you cant shoot a 357 mag in a 38 special. Hope I helped

I may be wrong, but aren't 5.56 and 7.62 nato, while the same dimensions, spec'd to higher pressures than .223 and .308, making them unsafe for use in some of those rifles?
