I've got a couple of 30 round plastic 10/22 magazines from Cheaper than Dirt-the cheap ones that go for $8.97, CTD #MAG-416. Have not experienced any feed problems that can be traced to the magazine. I've learned long ago when you buy "cheap", and the ones I bought are cheap, you get what you pay for. If "ANY" issues arise from these mags that can't be fixed/ resolved, I'll simply pitch them and maybe consider buying a better quality 30 round magazine. Also, since I installed a Timney Trigger Block with modified magazine release, the ten round magazine change-out cease to be any issue at all.
