All of my .22's will shoot shorts or longs. They may not cycle the action or feed from the magazine, though. I have reliably shot .22 shorts from several different revolvers over the years. That's my preferred method of dispatch when running my trap line, as they usually make one neat round hole in the head and don't exit, thereby not damaging the fur. If your revolver is spitting lead, it's likely out of time and has nothing to do with the ammo. I have three 22 revolvers, and all shoot shorts, longs, long rifles, cb's, and colibris without an issue. My little Phoenix pocket pistol will even shoot colibris, though it won't cycle them. Still, fun to "play" with them; almost like making your 22 into an air rifle/pistol.
I have a 514 Remington that I only feed shorts, and as such can't chamber a Long Rifle cartridge due to the fouling ring in the chamber. I've intended to clean it, but think why bother? Simply because all it will ever shoot is shorts as its sole purpose in "the collection" is to remove offending varmints from my yard/chicken house/garden. And it does so with aplomb. Of course, I have my Henry and my Remington 572 that I love to shoot shorts through. As a matter of fact, I have probably shot more 22 shorts than LR's in my lifetime, since when I was a kid that's all I could get! And to this day, I still like to shoot them.
