Soviet 7.62x54r 7n1 markings


Does anyone know why the Soviet made 7.62x54r 7n1 “sniper” load has no identification markings at all except for the packaging? Once outside of it’s packaging, you can not tell a 7n1 from a standard LPS ball cartridge (later production after the silver tip color code was deleted). Seems that this was done on purpose for some reason, but why?
