Hi folks,

Subject says it all. My stepdad has a 1944 Iver Johnson revolver chambered in .22 Long. Do you know what the .22 Long is? I do, and it's hard to find this ammo these days. Be nice to use .22 Long Rifle in it, but I can't find any info on using .22 LR in the revolver.

Anybody have any experience with this? Any reason not to use 22 Short? I don't have the gun in front of me, but I'd think that maybe the cylinder's too short for .22 LR.

You can use 22 long, short and CB caps without a problem. The 22 long rifle uses the same case as the 22 long, it just has a heavier bullet and originally the exact same powder charge.

Usually pressures are not high enough in any standard velocity 22 LR round to hurt your gun.

I had a Win. 1890 chambered in long once. I may still have a few boxes hiding somewhere.

Originally the 22 short used a 29 grain bullet and 4 grains of "blackpowder" type gunpowder. The original 22 long used the same 29 bullet but 5 grains of blackpowder and the 22 long rifle used a 40 grain bullet and 5 grains of blackpowder
There was also a 22 Extra Long, which had a 40 grain bullet on 6 grains of blackpowder

So the 22 long was actually faster than the 22 long rifle

But then 'smokeless powder' was invented, and it was great stuff, almost twice as potent, and then 22 long rifles were loaded hot enough so they were faster than 22 longs.

If your gun cannot chamber the .22 long rifle, then I guess you have to use old .22 long if you can find it. Otherwise, use .22 short or look into the overall lengths of all the commercially available .22's (except .22 Magnum) and find one that fits inside your chamber properly. Remington makes a sub-sonic, CCI has mini mags, shorts etc. Good luck and be safe.

As I recall CCI makes a .22 long round still.

Thanks! Found it on MidwayUSA and ordered a case shipped to my step-dad.
