hello
I have used the Ceiner conversion kit in a .223 Bushmaster rifle and it was very ammo sensitive. The PMC zapper solid tips worked the best for me and I noticed since a .22lr gets dirty often, it would jam some after 50-75 rounds. Cleaning it made the jamming go away. A friend of mine told me to use only copper plated tips in these types of guns including your Bushmaster because lead bullets would be soft and sometimes make jamming alittle more easier to happen.
