I had my 10 y/o daughter out today shooting the 10/22. She did a great job! We fired 150 rounds or so with no malfunctions so I really am feeling like I agree with those who say it is like flipping a coin. I do like the extra reliability of a centerfire cartridge though..... decisions, decisions! lol
If you do decide on a 10/22, I would not recommend Stingers as a SD cartridge. The slightly (very slightly) longer case length can cause problems. I'd stick with a high quality hyper velocity LRN 22LR.
