Gonna load .308 using 7.62x51 military LCLR brass with ramshot tac and 150gr Hornady Fmjbt. Should I load using .308 load data at the lowest and work up? Or should I minus 10% off the lowest to start? Gonna use the load data from ramshot btw. I understand 7.62x51 brass is thicker. Just want to be safe. Thanks guys.
