Heres an odd one I picked up the other day, didn't realize exactly what it was till I got it cleaned up. I was puzzeled when I looked at the end of the barrel of this neat 22 and saw the muzzle was approx 410 size. I did a little research and discovered it was quite a rare find, the 22 shotshell routledge barrel was made for indoor skeet. They called it Mo-Skeet-O, they shot 2" skeet with it. I'm still trying to figure out the date code. The only 510s that were rarer were the ones that actually had Mo-Skeet-O written on them
I'm going to try it out with some shot shell next weekend, see what kinda pattern it makes. An oldtimer told me they used to use #10 in 22 shot shell, all I could find was #12
picked up a 290 WInchester 22 and a Ward Model 60(Stevens620) 12 gauge pump with two barrels along with the Remington
