I think you guys are waaay ooooofff base. Ive had 10-22s and they frequently jammed.
Most guys in North America wouldnt know this but BRNO Model 581 hands down the most reliable 22 in the world. Bar none.
I have had 2 of these for most of my life and would not let them go for anything.
Since these guns never ever jamed we decided to test one out to see how far it would go. We shot well over 700 rounds before the gun finally jammed. Now the funny part is that it only jammed because the chamber became so built up with lubricant residue that the round could not fit into the barrel. We pushed a cleaning rod through it and kept on shootin.
The design is simplicity itself as they come apart much like a mini 14. The bolt is free floated well clear of the reciever an runs on a bearing. Accuracy is also better than you would expect.
If you can find one buy it, you will not be sorry.
This is what they look like
