The Omega can handle 150 grains of Black Powder or Pyrodex equivalent, or three 50 grain Pyrodex pellets. With its 28" barrel, it burns magnum charges with maximum efficiency, producing higher velocities over standard length barrels. This translates into flatter trajectories and increased down range energy.
