Gun Club has revived doing Vintage Military Rifle Matches (1954 and below) after years of not doing them. Have never done one before but always wanted to. I am going to be going in with a Special Grade CMP M1 Garand. I have read the rules and qualifications and understand them. Beyond that, any do's and dont's so I don't stick out like a sore thumb as a first timer in this competition? Not with the M1 Garand, know how to use it.
