What's the draw back to using 22 shorts vs 22 long rifle in a Ruger Single-six, my new model is marked 22 caliber and not 22LR. it came with a second cylinder marked 22 mag. but the Ranger officer says it's 22 LR only with the first cylinder I've always thought shorts could be used in a firearm that was marked 22LR,kinda the same ideal as 38's in a 357. Am I wrong/missing something?????
