I am loading the above in new W brass in Bolt Action rifle. This is my first time loading 223 Remington. I would usually just shoot blue box Black Hills. Can I still load these long to just off lands? Also, I am confused about the wide disparity in load data. Even Sierras load data from its book does not match Its subscription load data. I am seeing max loads from 23.7, 24 and 25 gr. I am just looking for accuracy to 500 yards...any input? Shooting in DT 223 conversion w/bartlen barrel 24”.
