I bought one of the Norc JW 20's, new, 3 or 4 years ago.
It fired so accurately and so reliably that it was almost boring. I decided to try to get it to fail. I repeatedly loaded that thing with every piece of crap .22 (some of 'em green, some of 'em greasy, etc.) I could find, brands etc. mixed up together. I failed, utterly, trying to get it to FTF, FTL, FTE, etc. I swear, that little JW 20 will fire ANYTHING without issue. It breaks down into a really small package, too. Love it - a GREAT SHTF/backpack/camping gun, IMHO, and a spectacular deal at that price!!
