Last I knew, the Saratoga club was run by the Schreiners and races/training was on their property. If Curt and Jim Jr. are still around that means you are rubbing elbows with some of the better biathlon talent the US has seen. Safety training was available only over the summer for a long time and hopefully that has changed. The national guard will often supply rifles for the safety and intro events, so it may depend on when the guard guys/gals are around. I'm pretty sure Curt was on the Guard team as well as US, so they prolly have good access to rifles. Right now, the elites will be hitting the race circuits in Europe and Yellowstone.
I would try to call Jim Schreiner, who lives on Starr Road off the Sacandaga Lake, if no one is available from the web site. If needed, I could try some old contacts for you.
