Publication number: 20190204051Abstract: The present disclosure provides a cartridge that modifies the .223 cases to achieve a cartridge length of 38.3 mm for use with a bullet (e.g., 110 g). The present cartridge system allows the use of a 30-caliber bullet to be used in an AR15 rifle/pistol platform. The decreased cartridge length optimizes the powder burn rate and pressure, which in turn has a greater effect on the ballistics of the round. The present system yields 300-400 ft/s higher velocity over the .Type: ApplicationFiled: January 3, 2019Publication date: July 4, 2019Inventors: Greg Franklin, Chris Betley

Publication number: 20190204055Abstract: An obturator ring (4) for a mortar round (2) is proposed where the geometry of the ring (4) is modified by its sliding and striking stationary anvil (18) when the round (2) is placed in the muzzle-loaded mortar's barrel (6) and reaches its bottom. The initial ring (4) geometry does not impede round's travel down the barrel (6) while its modified geometry provides a gas seal between the round (2) and the barrel (6) wall. Several embodiments featuring free-rotating (4), splined non-rotational (4a) and stationary separated (12a-14a) designs are presented. The ring works with both smoothbore and rifled mortar barrels and in several embodiments imparts rotation to the round (2) if used in a rifled barrel (6). An optimized muzzle-loaded mortar barrel (6) operating in cooperation with rounds equipped with the obturator ring of instant invention is also presented, containing rifled (6a) and smoothbore (6b) sections.Type: ApplicationFiled: January 3, 2018Publication date: July 4, 2019Inventor: IGOR ABRAMOV
