摘要： An improved pellet form for achieving relatively high muzzle velocity when discharged from the barrel of a gas rifle, particularly a high-performance air rifle, has a pellet head portion of any suitable profile and diameter providing a free-sliding but close fit for the nominal barrel bore, e.g. the 0.177 and 0.22 standard bores, and has a conventional rearwardly-flaring skirt of conical shell form; improved early gas sealing and improved swaging of the skirt margin is induced by novel bevelling of the inner surface of the skirt margin, the trailing edge being tapered to a thin annulus, while the outer surface of the skirt has a terminal portion formed with conical apex angle greater than the apical angle pertaining to the major length portion of the skirt forward of the trailing edge. The skirt edge is initially an interference fit for a diameter comparable to the diameter across opposed rifling grooves, and is a light force fit into the nominal barrel bore diameter. Intimate molding of the skirt margin achieves rapid early sealing, preventing blow-by of gas, while drag is relatively low due to the restricted area of metal which is gas-pressed against the barrel wall. Tests verify significantly flatter trajectories and higher penetration energies for pellets according to the invention.

摘要： A pellet for a compressed gas powered weapon, such as a pellet gun, is disclosed. The pellet includes a forward head portion, a rearward tail portion having a hollow propulsion gas pocket, and an intermediate waist portion, the head portion having a front end, a centrally positioned penetration point protruding from the front end and a blade having a cutting edge extending between the penetration point and the front end for promoting penetration of the pellet into a target and improve penetration in addition to a shock wave generated by the front end.
