The Crosman 760 doesn't shoot Bullets it shoots BB's or .177 caliber Pellets.
The Crosman 760 Powermaster was made from 1964 until 1991 in about eight different variation's. Today it called the 760 Pumpmaster. The rifle was never very expensive and a brand new collectors edition cost $85, but most new 760 will cost around $60. To find an old one I would try Craigslist or gunsamerica. The version you want is the 5th edition 1977-80 that had manual cocking. Good luck.
