technically the 308 and 7.62x51 are different, and Savage chambers for 308 Win.
My understanding is the 7.62x51 is safe in a 308, but don't quote me on that. I know 5.56 is not safe in a 223 due to higher preasures and I think 308 & 7.62x51 is the other way around. Do a search in the forum this was discussed not to long ago.
