Definitions

  • This invention refers to a lead bullet with plane base and base spoke whose obvious objective is its quality of being able to be shot by any type of bore for metallic cartridges, furthermore having at disposal a high stopping power and, at the same time, an adequate penetration and perforation.
  • cartridges have nowadays more and more success for multiple uses in small calibers.
  • the cartridges of caliber 22 are normally employed for small game, shot contests, subcalibering, spiking, etc.; these cartridges were designed in 1857, being employed in a determined model of revolver manufactured by the company Smith & Wesson, now being able for an exchange with pistols and revolvers from different origins.
  • caliber 6,35 mm is still being manufactured in big quantities, being provided with a cap primed with unoxidizing Tetrinox, noncorrosive and nonmercurial.
  • the cartridge of 38, short and long type have a lot of supporters, but, obviously, the short type is already obsolete and at present out of the manufacturing programmes.
  • none of the above mentioned types has a cartridge provided with a plane base for the purpose of favouring the setting of the propelling charge and the uniform pressure of the games during the combustion, with a base spoke which facilitates the alignment of the bullet in the charge and, at the same time, with a wide and deep oil duct.
  • the lead bullet with plane base and base spoke proposed by the invention constitutes an extremely simple solution and, consequently, of low cost, easy to implant, land offering total guarantee and advantages not considered until now in the conventional cartridges.
  • the bullet proposed by the invention is provided with a plane base favouring the setting of the propelling charge and the uniform pressure of the gases during the combustion.
  • This bullet has a base spoke which facilitates the alignment of the bullet during the charge, and, as a consequence, favours the ballistics at muzzle by eliminating the material removal produced by the combustion gases in the bullets with angle base, especially in those bullets using lead alloys in their configuration.
  • This characteristic may be easily checked, since this bullet does not leave any residues of lead material on the muzzle plane of the barrel.
  • this plane bullet is the fact of being equipped with a wide and deep oil duct in order to avoid the leading or storage of residues in the bore of the weapon, this duct furthermore constituting a separation mean for the two rifling zones of the bourrelet.
  • this oil duct can be optionally filled or not with bullet grease.
  • the bourrelet is composed of two widely separated zones, as a consequence of the above detailed oil duct, so that it is achieved a perfect centering and guidance of the bullet with a friction decrease.
  • the crimping or fastening channel is wide and deep, having a separation zone between the bourrelet and the driving-band.
  • the driving-band has the main mission of correcting the oscillations in the chamber, or upon inlet in the junction cone of every shot bullet, forcing the coincidence of the bullet centerline with the bore centerline.
  • the driving-band becomes also a bourrelet, so that this band means more than 62% in length of the total bullet length.
  • the spoke that allows the adequate interrelation with the junction cone of the bore is also adequate for preparing the task of the driving-band.
  • the sphere radius on the head is in conjunction with the cone frustum, fact that motivates the deformation of the bullet ogival head, by virtue of the adequate shock wave that it produces, so that a development of an adequate terminal ballistics is given, goals to be met by a police or defense bullet.
  • This lead bullet with plane base and base spoke may be conformed with any material, metal or alloy suitable for ballistics.
  • the center of mass is slightly backed up.
  • the stopping power of the bullet is very high, while it also has an adequate penetration and perforation.
  • this bullet may be shot with any type of bore for metallic cartridges (rifled, polygonal, combined) without damaging the bore, this not being the case in the present solid bullets because of the quick wear of the polygonal and combined bores with the subsequent ballistic death.
