I know of a M1 carbine that was destroyed by the Chinese LC52 ammo. The lugs on the bolt were sheared off and the lug seats in the receiver were sheared off as well. I shot a box of it once not knowing it was Chinese counterfeit stuff and my M1 carbine developed cycling issues after use. I had to clean out the gas port to get it to work again. If you have the stuff I would recommend not shooting and pulling the bullets to reload with a new case and charge of known powder.
