You may want to check that LC 52 before you fire it. LC made ammo in 1952 with silver and gold primers with most being the silver color BUT the fake Chinese made LC 52 all have gold colored primers which are considered to be corrosive. If you can pull a round to be sure. It will have the two small flash holes of a berdan primed case which would be the fake Chinese made ammo and you don't want to shoot any of it. One centered flash hole would be for a boxer primer and would be the real LC ammo.
