22 Long vs 22 LR

[drilldaddy78]

Hey, semi newbie here on Calguns. I am trying to find a little info on these two rounds. As far as I can tell the 22 LR has a longer heavier round than the 22 Long. I am wondering if the 22 long will fire in my Sig Mosquito. It is not too ammo picky since I polished the feed slide and such. Any input will be helpful.

I can't say for sure, but I wouldn't run a 22 long in something that was designed for 22lr. Someone pls correct me if i'm wrong.

They're different, not up on the "specs" but don't expect 22 long to cycle. Natchez has some fed automatch its a bit pricey, but they had it a few mins ago.

I was at my range a few months ago and a gentlemen was having problems with his SR22 loading ammo. End result was that he was shooting CCI Long ammo. Gave him some .22lr High Velocity and problem solved.

.22lr(long rifle) is longer then a .22 long. You can fire a .22 long in a .22lr gun but it most likely have failures to feed. I shoot cci cb longs in my S&W 22a but I have to single load them.

.22 longs should feed and shoot fine in a bolt action or lever action.

[Annex138]

.22 Long is a variety of .22 caliber (5.6 mm) rimfire ammunition. The .22 Long is the second oldest of the surviving rimfire cartridges, dating back to 1871, when it was loaded with a 29 grain (1.9 g) bullet and 5 grains (0.32 g) of black powder, 25% more than the .22 Short it was based on. It was designed for use in revolvers, but was soon chambered in rifles as well.[1]

In 1887 the .22 Long case was combined with the heavier 40 grain (2.6 g) bullet of the .22 Extra Long of 1880 to produce the .22 Long Rifle giving a longer overall length, a higher muzzle energy and superior performance as a hunting and target round, rendering the .22 Long and .22 Extra Long obsolete. For a time there was a price difference between the .22 Long and .22 Long Rifle and the .22 Long held on with budget minded shooters until the price advantage finally disappeared. No new firearms are designed specifically to use .22 Long and the largest 3 producers of .22 Long ammunition ceased production (although it continues to be made by CCI, Aguila, and others). Many .22 Long Rifle guns will chamber and fire the shorter round, though the .22 Long generally does not generate sufficient energy to operate semi-automatic guns. The one prominent survivor of the .22 Long is the .22 CB Long, a long-cased version of the .22 CB.

While the original .22 Long loading used the same powder charge as the .22 Long Rifle, the .22 Long bullet was significantly lighter, and the combination did not result in higher velocities for the .22 Long when fired from a rifle. The large barrel volume to chamber volume ratio of a .22 rimfire rifle means that the powder gasses have expanded as far as they can well before the bullet reaches the muzzle of a normal length rifle barrel, and the light .22 Long bullet has less inertia than the .22 Long Rifle. This means that the .22 Long bullet (and to a lesser extent the .22 Long Rifle in most loadings) actually slows down significantly before it exits the barrel.

Since the .22 Long Rifle performs as well in a short handgun barrel as the .22 Long and outperforms it significantly in a long rifle barrel, the development of the .22 Long Rifle assured the .22 Long's path to obsolescence.

In a sense, though, descendants of the .22 Long still live on, though they are not sold as such. Modern Hypervelocity loadings of the .22 Long Rifle use bullets as light as 30 grains (1.9 g), and special blends of powder to make full use of a rifle barrel to generate velocities far higher than normal loads, and chamber pressures high enough to cycle semi-automatic firearms reliably. The most well known of these is the CCI Stinger, which actually goes so far as to stretch the case length slightly, so that with the short, light bullet, the overall length is still within the max overall length for the .22 Long Rifle.

You know, you could have just posted a link to the wikipedia article instead of just copying the text of the whole thing while pretending you wrote it.

Dude, chill out. I never claimed to write that. Just trying to post some info to help out.

[drilldaddy78]

Thanks for the info guys.

Wondering why would they name a new round long rifle when instead of something else when there are .22 LONG existing already

.22long will work FINE in a 22lr gun, it's like shooting 38special in a 357mag revolver. But it won't cycle. i use CCI 22long subsonic in my 22lr revolver, i use it sometimes in my auto pistols but i had to rack the slide everytime i shoot.
