1: In one of the 10/22 that is setup for .22 WMR could you also fire .22 LR out of it without modification?

2: If so would it also accept the regular 10/22 .22 LR magazines or would you have to use the .22 WMR Magazines?

I want a gun you can fire .22 LR with a 50-round magazine, as well as fire 22 WMR, and .17 HMR (with a different barrel for the HMR of course).

No. 10/22 is for .22LR only. 10/22M is for .22WMR only. The rounds are not interchangeable and each rifle uses a differnet magazine. The .22WMR is a longer round than .22LR.

But I have seen guns that .22 shorts and .22 LR out of the same gun, but the ones ive seen have always been tube feed. . . shouldnt the same principal apply to .22 LR and .22 WMR.

Nope, as JBP said the rounds are not interchangeable.

The dimensions of each round are different enough to make them unsafe to try to do that (the WMR is slightly larger in diameter to prevent chambering in a firearm designed for .22 LR). A .22 LR will slide into a .22 WMR chamber, but it is quite loose and there is danger of case splitting, failure to extract, failure to fire, etc.

The .22 Short and .22 Long are based on the LR and are usually compatible in firearms set up for .22 LR. Some firearms state that they are made to fire .22 LR only (the 10/22 is one). They will usually fire a Short or Long safely, but the action or feeding mechanism may not be able to function properly with them.

ok, thank you.

Bob,
Although it seems logical that if you can use .22 Shorts in a gun chambered for the .22 Long Rifles, you could use .22 Long Rifles in a gun chambered for the .22 Magnum, it's not true. The .22 Magnum (WMR) is a different type of cartridge than the various other .22 rimfires. If you examine a .22 Magnum cartridge closely, you'll see it has a jacketed bullet and the cartridge case is bigger around than the bullet. Unlike the various other .22 rimfire bullets, the .22 Magnum bullet isn't "heeled" - that is, it's straight-sided from the ogive down to it's base. The part of a .22 Long Rifle bullet sticking out of the cartridge case is the same diameter as the cartridge case itself because a .22 Long Rifle bullet is "heeled" - meaning the part inside the cartridge case is smaller in diameter. Essentially, that means the .22 Magnum cartridge case is bigger around than the .22 Long Rifle cartridge case. Also, the .22 Magnum bullet is a couple of thousands of an inch bigger around than the .22 Long Rifle bullet. It's not much bigger around though. The Ruger Single-Six revolver is one gun (I'm sure there are more) that can be used for both .22 Long Rifles and .22 Magnums because, and ONLY because, you can get it with two different cylinders. :)

Sorry Bob - it looks like I got scooped. I should learn to type faster.

Actually you can take a 10/22 and have it shoot 22lr, 22mg, and 17hmr, it just requires a little heart and modification. Guides and extensive testing found at the forums on
