Saturday is the practice day, which is the day to come out and practice with whatever rifle you have (30-06 and down). Make sure you are zeroed at least to 100 yards, or everyone will be waiting on you to zero. If you're not a member or military/DOD/veteran, then you will need a sponsor, which there are members here that will help. Sunday is the CMP EIC match, service rifle iron sights only (regulation M1 Garand, AR15 20" barrel, M14/M1As) and you have to shoot the match course. Saturday/Sunday will be a long day, and you are required to stay the entire time, registration at 7am and cleanup and end around 1pm or so.
