摘要： A cartridge comprising an elongate rifle bullet with a plurality of circumferential grooves having overmolded polymer therein defining embedded polymer rings. The cartridge further having a case and propellant. The polymer rings have an outer surface that is flush with, that is, conforming to the outer surface of the body. The polymer may have be selected to have a favorable coefficient of friction with respect to the barrel. The bands offering reduction of the metal to metal contact between the bullet and the barrel while not diminishing the ballistic coefficient of the bullet.

摘要： Modular cartridges are disclosed that can be initially assembled, disassembled, and reprocessed by hand. The cartridge case is suitable for use with a variety of projectile designs and weights and for use with a range of propellant amounts and primer types. The variety of projectiles and range of propelling forces permits the present invention to provide cartridges for all types of uses, including indoor and outdoor target shooting, training, non-lethal self-protection, and lethal uses. The cartridges include a case, a projectile, a primer, and a selectable amount of propellant (if any), and primer housing insert” and which is configured to be releasably attached to the striking end of the case and to contain the primer and the desired amount of propellant.
