cartridge generally is loaded with a 50-gr. full metal-jacketed bullet. Muzzle velocity is around 760 ft/sec. A limited production of cartridges loaded with a hollow-point jacketed bullet was made by Winchester in the early 1970s. All these cartridges were loaded with ball powder. These bullets as a general rule do not expand in the body. In 1981, Winchester-Western introduced a cartridge loaded with a 45-gr. expanding-point projectile. The bullet is lead, unjacketed, but coated with a copper Lubaloy® finish. The bullet has a hollow point filled with one No. 4 steel birdshot pellet.
