Probably a defective bullet, thinner than needed jacket or out of balance. I seriously doubt this is any reflection on quality of the rifle.
I knew a guy once that had a bunch of these once. He was trying to hot rod a .17 Remington.
Useless, and kind of funny, but it never really hurt anything.

Liberals are constantly telling us about the poor and oppressed in this country. With that in mind, why do they feel the need to keep importing poor people from other countries?
