I'm looking in my Modern Reloading (2nd Addition) by Richard Lee and it says a .308 bullet is actually .308 in diameter. When I was looking on the Lee site for bullet molds, the only 30 cal. molds they have are .309 in diameter. When i thumbed through the manual, I couldn't find any 30 cal. bullets that were .309 in diameter.... what gives? Wanna kill these ads? We can help!
