Hornady LEVERevolution Ammunition 357 Magnum 140 Grain Flex Tip eXpanding (25pk)Ever since its introduction in 2006, LEVERevolution ammunition has brought grandpa's lever action rifle out of retirement and turned it into a firearm everyone is shooting. Featuring a soft polymer flex tip, it's tough enough to stand up to a jacketed bullet, but soft enough so it won't dent the primer of the round in front of it or cause accidental firing in a lever gun. This new technology makes LEVERevolution cartridges safe in tubular magazines.
