Places that stamp them 7.62 nato or whatever still test them to 308 win saami specs it's just a sales thing. There's only one rifle I know of in the entire world that is 7.62 nato but not safe with 308 win and that's some sort of Indian Ishapore Enfield somethingrather rifle.
edit: 762nato spec was like 53k PSI, SAAAMI spec is 58k psi I think. Like I said it's nothing to worry about with a modern firearm barrel.
