58 gr of Ramshot Hunter behind 180 gr accubond. Lit with remington 9 1/2 magnum primer. 2725 fps chronographed 24 inch barrel. 4 inch groups at 500 yds. 12 inch groups at 500 with standard primer( inconsistent ignition) load taken from nosler 6 reload guide with exception of magnum primer. 58 gr is Max load in nosler guide but pressure appeared low to moderate. I didn't go beyond 58 gr because I am fairly knew to reloading. The load was consistent in a variety of temperature and weather condition 0 to 60 degrees
