my 10/22 has run pretty good. aside from cheap ammo its gone through everything I stuck in it without a hitch. even picked up some aquila colbri ammo for it. stuff is quieter than my shrouded air benjamin discovery but it doesnt hit quite as hard. have to say I have been really surprised at what airguns are capable of. my 10/22 might get a bit dusty if I keep tinkering around.
