.22lr/.22mag

[Spooler41]

I posted a similar question on face book's .22 group
and it vanished?
The question was, I over heard a question at my LGS
about shooting .22lr in a .22mag revolver ,as in
fireing .38 special in a .357 mag. It seemed to stump
all within ear shot . No one had an answer ! Is it safe?
Is there any reason to not do this ? And under what circumstances might it be Ok !

"The .22 WMR uses a larger case than the more popular .22 Long Rifle, both in diameter and length. The .22 WMR case is a lengthened version of the older .22 WRF. In the most common modern loadings, the combination of more powder and higher sustained pressures gives velocities of 1,875 feet per second (572 m/s) from a rifle using a 40-grain (2.6 g) bullet, and 1,500 feet per second (460 m/s) from a handgun. Because of its larger size, a .22 WMR round will not fit into the chamber of a .22 LR firearm. It is dangerous to chamber .22 LR rounds in a .22 WMR firearm. Doing so can result in injury from high pressure hot gas leaking around the LR case, which is too small for a .22 WMR chamber."

Gee whiz, common sense should prevail here, two cylinders are not provided just for the hell of it. Ever see a two cylinders come come with a 38/357? Not unless it's a 9mm too, and even then not always depending on how it is headspaced, ie: the Medusa.

There is an incredible amount of ignorance in the gun world as well as a great deal of misinformation. As has been said: "There are no stupid questions but there are a lot of stupid answers!". I would recommend that you don't accept the first answer. Since you have a Smith and Wesson I'll make reference to that gun. Smith and Wesson uses a barrel that is .222 for their .22 Rimfire guns and a .223 for their .22 Magnum guns - such as yours. This means you can shoot the .22LR rounds in a .22 Magnum gun but they don't recommend shooting the .22 Magnums in a gun chambered in .22LR. Smith and Wesson won't even fit a .22 Magnum cylinder to one of their .22LR guns. I don't know if they will even fit a .22LR cylinder anymore. There have been enough modifications made to the newer guns so the newer parts simply will not fit. I hope this helps.

I know two shops in the PA area that if there are five people standing at the counter you should have your rubber hip boots on.

Gun ignorance is not limited by employment. I've known some truly ignorant LEOs - especially about firearms Laws and especially those related to Concealed Carry.

The BS can be pretty deep on both sides of the counter.
