Leverevolution represents a breakthrough in ammo design for lever action rifles and revolvers.The key to its innovation and performance is the patented elastomer flex tip technology of the ftx and monoflex bullets.Safe to use in tubular magazines, these bullets feature higher ballistic coefficients and deliver dramatically flatter trajectory for increased down range performance.Its propellants provide maximum muzzle velocity at conventional pressures, resulting in flatter trajectories and more downrange energy.Caliber: 338 Marlin ExpressBullet Type: Flex Tip eXpandingBullet Weight: 200 grMuzzle Energy: 2922 ft lbsMuzzle Velocity: 2565 fpsRounds Per Box: 20Boxes Per Case: 10Application: Performance,ProtectionCasing Material: BrassHazair: YesAmmunition cannot be shipped to a P.O.
