Longitudinally sectioned firearms projectiles

A penetrable projectile structured to be discharged from a firearm, said penetrable projectile comprising a longitudinally sectioned body of at least two body sections, said at least two body sections being radial sections of said penetrable projectile, each of said at least two body sections comprising at least one interior surface that runs in the tip-to-rear/front-to-back direction of said penetrable projectile, said penetrable projectile further comprising at least two binding/holding elements, including at the tip and at the rear of said penetrable projectile, and disposed in radially surrounding relation to said at least two body sections, said at least two binding/holding elements structured to provide controlled rupturing of said at least two binding/holding elements responsive to said penetrable projectile striking a predetermined target, said penetrable projectile further comprising a central exterior surface disposed and dimensioned to reduce the area of contact with the rifling of the firearm, said at least two binding/holding elements maintaining said at least two body sections in synchronized rotation while being fixedly secured to one another by said at least two binding/holding elements whereby upon said penetrable projectile striking said predetermined target said at least two binding/holding elements rupture in an at least partially controlled fashion, thereby separating said at least two body sections of said penetrable projectile and delivering at least one reactive chemical substance or explosive material supplemental payload contained within at least one central/interior, non-peripheral cavity of said penetrable projectile, and any additional supplemental payload contained therein, to/within said predetermined target to cause damage additional to impact and penetration of said penetrable projectile.

An ammunition cartridge comprising a projectile slideably disposed within said ammunition cartridge, said projectile being radially sectioned and longitudinally sectioned lengthwise along its entire longitudinal length by being divided by at least one plane in a tip-to-rear/front-to-back direction of said projectile, said projectile comprising at least two longitudinal body sections, said projectile further comprising at least two exterior binding elements, including at the tip and at the rear of said projectile, that hold said at least two longitudinal body sections together at least before impact with a target, said projectile further comprising at least one supplemental payload contained within a central/interior, non-peripheral cavity of said projectile to protect said at least one supplemental payload from contact with/exposure to said projectile's exterior before reaching said target, said at least one supplemental payload comprising an at least one reactive chemical substance or explosive material not involved in the firing or propulsion of said projectile to said target, said ammunition cartridge structured to discharge said projectile from a firearm and capable of delivering said at least one supplemental payload to/within said target as said at least two longitudinal body sections separate to cause damage inside of said target additional to impact and penetration of said projectile.
