than it should work
while the bolt is out stand the rifle up with the chamber up, drop a shell in the chamber, it should drop in all the way, and should drop out when you invert the gun, or with out any force, depending on how tight the chamber is.
I see many 22's with what looks like a clean chamber , that has grease , carbon build up, and the shell will stick in the chamber.
Will drop in part way , them get stuck, and the bolt forces it in and you end up with your problem.
Different ammo can give trouble as well, try something else, You may have tried that , forget if you said or not.
