20090293755 | Partial decomosition with a massive core and core made of pressed powder - The decomposition of a projectile in a target body, particularly a hunting projectile in wild animals after penetration therein, determines the energy output of the projectile and thereby the effect of the shot. For projectiles with double cores, the properties of the ingredients used in the cores decisively affect the decomposition and particularly the deformation behavior of the cores. According to the invention, a partial decomposition projectile comprising two cores is provided with one solid core ( | 12-03-2009 |

20140230683 | REDUCED FRICTION EXPANDING BULLET WITH IMPROVED CORE RETENTION FEATURE AND METHOD OF MANUFACTURING THE BULLET - A low-cost, reduced friction expanding bullet with an improved core retention feature and a method of manufacturing the bullet is described wherein a cylindrical jacket containing a compacted malleable metal core having an open end and a closed end is forced into a forming die having a bottleneck shaped interior resulting in a bottleneck shaped pre-form wherein the outside diameter of the open-ended forward portion of the jacket is smaller than the outside diameter of its closed rearward portion and wherein a transition shoulder separates the two diameters. The pre-form is then placed in a profile die wherein a base punch exerts an axial force against said pre-form which axially collapses a portion of the jacket wall forward of the transition shoulder subsequently forcing said portion of the jacket wall radially inwardly providing a reduction in bearing surface and forming an internal core-locking radius while at the same time forming an ogival bullet nose. The bullet thus formed provides reduced friction and ultimately higher muzzle velocity per any given chamber pressure level while also providing a core-locking feature comprising a wide-area, circumferential indentation which serves as a living hinge that ultimately expedites uniform bullet expansion. | 08-21-2014 |

20080216700 | Lead Free Monobloc Expansion Projectile and Manufacturing Process - The present invention relates to a bullet made of a single solid piece of deformable metal, containing no lead or toxic material, easily deformable but without fragmentation in a soft environment with a high rate of energy transfer, and a high level of solidity in hard targets, retaining most or its total initial weight while penetrating those targets. Said objects are achieved by constructing a solid monobloc bullet with a cavity on the longitudinal axis which is opened towards the fore end of the bullet. The method of construction encompasses a sequence of simple operations: cutting of a cylinder blank of soft material, forming a cavity centered on the longitudinal axis, and forming an ogival or conical form, with external pre-cuts to foster an homogenous deformation. The present invention applies to any handgun, rifle or shotgun ammunition; when used in smoothbores, the essential stability of the bullet is achieved by positioning the center of gravity ahead of the aerodynamic cent | 09-11-2008 |
