I recently read in a GunBroker ad that a .223 caliber in a Ruger#3 is rare. That doesn't seem very likely to me. My older issue of "Guns & Prices" gives no indication to support this. It does say to add a premium for "neato" calibers-- any idea what that refers to? Does anyone have any data to support the .223 rare statement? My curiosity runs deep on this one. I look forward to your ideas and knowledge.
