RE: Utilizing 307 load data for 308 cases?
I can tell you this firsthand from loading the 307, 308 and 30-06, load the bullet to the cartridge specs, i.e. use the 308 data. At respectable ranges the 30-30 bullet will perform just fine at 06 and 308 velocities. It may not like the hotter loads just start from the low end loads and work your way up, you probably won't achieve the same velocities but you won't lose that much speed.
