Sacrilege of sacrileges but I've given up the 10/22 for a Remington 597, and CCI Stingers are the only ammo that will reliably feed from the horrid Remington mags, but when it DOES work it puts my old 10/22's to shame with regards to accuracy.
Anyhoot, $110 bucks plus shipping isn't bad at all for a brandy new tube which is why I'm passing it along.
