| 21 | Caliber shell with rigid mounting to housing of stabilizing fins | US15321018 | 2014-08-26 | US09958241B2 | 2018-05-01 | Renat Abdulberovich Yusupov |
| The invention relates to ammunition for firearms, as smooth and a rifled barrel. The projectile with rigid attached to the housing stabilizing fletching block, plates of fletching block have a continuation on the housing, centering the projectile in the barrel. In the offered variant, on the friction and heat of the bullet and the barrel takes about 1% of the shot energy, besides low vibration. The rest of energy escapes to destination, and that's good. Erasing minimal of the barrel. Application of the projectile in the shotgun and rifle barrels increases the service life of barrels. Use of such projectiles increases the initial speed, and with the sleeve-nozzle and a second charge, allows to increase the speed and specialization of the projectile. At the expense of the aerodynamic and gyroscopic effects, increases the lethal effect over long distances, due to the greater energy saved, improve the close grouping of shots and flat trajectory. | ||||||

| 28 | Pilum bullet and cartridge | US14095745 | 2013-12-03 | US09644929B1 | 2017-05-09 | Michael Sean Bradbury; Darrel Ray Barnette |
| An improved sub-sonic cartridge for small arms containing a bullet whose Calibers (length/diameter) value is 6.0 or greater, which imparts to the bullet substantially greater kinetic energy than smaller and lighter sub-sonic bullets. The greater kinetic energy of the bullet aids in cycling the action of semi and fully automatic firearms as well as imparts greater kinetic energy to the target upon impact. The bullet incorporates an fin unit on the aft portion of the bullet; the aft fin unit is rotationally independent of the rotational state of the bullet in flight. The fin unit forces the Center of Pressure rearward of the Center of Gravity for added stability and accuracy in flight. Volume vacant of propellant within the cartridge shell may be occupied with a durable and heat resistant material to aid in consistent and reliable propellant burn when fired. | ||||||

| A projectile having a fin deployment system disposed about its circumference. The fins are initially contained by a fin cover that is removed by aerodynamic force. The fins are then rotated around a rotational axis parallel to and offset from the central axial axis of the projectile body by the centrifugal forces created by the rotation of the projectile as the projectile passes through a barrel of a gun system or tube launcher. The fin deployment system can also have locking systems that lock the fins in the deployed position and prevent the fins from rotating back into the retracted position after deployment. | ||||||

| A bearing system for a spin-stabilized projectile including bearing configurations that permit selective relative rotation between a spindle and a body portion and which facilitate automatic centering of the spindle. Each bearing configuration includes a conical bearing surface rotatable with respect to a corresponding conical body surface. One bearing configuration is in a forward portion of the body portion and selectively engages a first body surface upon the projectile experiencing set-back forces to direct forces away from bearing elements, and another bearing configuration is in a rearward portion of the body portion and engages a second body surface upon the projectile experiencing set-forward forces to direct forces away from the bearing elements. Biasing elements work in cooperation with the bearing configurations to automatically maintain the spindle centered with respect to the body portion during pre-launch and in-flight and to re-center the spindle after set-back, balloting and/or set-forward phases. | ||||||
