RE: Utilizing 307 load data for 308 cases?
I think the 307 and 308 are the same except for the rim and the 307 was used in lever action guns like the 30-30 which is why the load data is less than the 308 and the bullets are similar to the 30-30. There should not be a problem loading them in the 308, just make sure the bullets are .308 diameter.
