My public range has a lot of milsurp shooters, so the Mausers, Mosins and Enfields are common. Seems everybody and his cousin has a Mosin M44!
But show up with a Swiss K31 or a Steyr M95, and it generates more interest!
Milsurp handguns are a bit scarcer, but one old gentleman commonly shoots his WWII-dated P38 and Luger pistols out there, along with his Japanese Arisaka rifles.
