As stated, the Hornady Manual has 6 pages of loads for different bullet weights. Everything I've read calls the shell dimension to be for a .310 bullet. Typically a .308 will fire fine and you will have to determine accuracy in your particular rifle. When I called Hornady inquiring about a .310 bore they said if the bore was on the upper side of tolerances you could use the bullets designed for the .303 British shell at .314 diameter. I asked about higher pressures from squeezing the bullet down to perhaps .310 or .312 and they said no problem, just don't start out with max loads.
