Can anyone tell me anything about some bulk 7.62x54r ammo with "TSS" and "76" headstamps? Recently acquired a Mosin M44 and a guy locally has some of this bulk ammo for sale. Tried a quick interwebs search, but no real luck finding any info on those headstamps. Hoping someone here is better at internet searches than I am. Really just curious to know how old this ammo might be and if it is Russian or what. Any help is greatly appreciated. Thanks.
