I've had mine for better than 15 years and shot untold thousands of rounds through it. Every once in a great while (like once a year, maybe) I'll hose out the action with wd40, wipe it down, put in a little oil, run a patch through the bore. I just do that because I feel guilty, not because it's malfing. I have a couple of those goofy banana mags and it will hiccup with those, but with the factory 10 rounder, it's 100%.
I've seen some complaints on this board and others about newer 10/22's, so maybe Ruger needs to look to their QC?
