Any autoloading .22lr firearm will be ammo-picky. I suggest trying a few different brands of magazines for your 10/22, as proper magazine fit and angle seem to be the key to optimum reliability with them.
First off, not any autoloading .22LR is ammo-picky. That's a myth, promulgated by those who justify poorly-designed and poorly-made .22s.
Ruger's own pistols will eat anything, and I mean ANYTHING that I feed them. I have three so far. One of them is set up for match shooting, with a 2X scope on it -- not only will it eat anything, but it will shoot many different kinds of ammo with match-winning accuracy, too. That's paid dividends over the past year, when you couldn't be too choosy about your .22 ammo and it was "shoot whatever you can find!"
The Marlin has been fine with anything I've fed it, as well, and will put 5 Mini-Mags into 1/2" at 50 yards off a rest.
