During 6 Minute sight in period before each relay, an unlimited number of shots may be fired and each is spotted. Coaching is permitted during this period. Many women shooters participated. Foreground at bench - Rosemary Conzo and her Husband Dan, July 1973. Next on bench two is Lance Heller, grandson of Leonard Heller with the famous wooden-shielded-barrel Rifle. This had two halves of wooden tube clamped to the barrel and can be seen in the large image if you zoom in on it. I'm told this rifle could shoot pretty well. Scope bases were glued into the wood.
