Have a whole bunch of IVI 5.56 brass prepped As it was free And plan to shoot it in a 223.. Usually use winchester or remington head stamp. This brass weighs more then remington and has less h20 volume . In my remington brass I shoot a lot of benchmark stocks 25.5gr with 50-52 gr bullets. How much lower should I go with this IVI brass as a starting point?
