I'd have to argue that point. My 10-22 was VERY accurate out of the box. It is quite capable a "dinging" quarters at 50yrds (I have the dented quarters to prove it!)
The aftermarket barrel has made it even more so!
As for proper cleaning, the 10-22 is a cinch to disasemble and clean.... Just takes a little practice. Easy to clean breach to muzzle.
That said, I think a bolt gun would be a better choice.... Like I said, my 6yo is getting one this summer (bolt gun, not 10-22).
JMHO
