Apparatus

A small arms bullet comprised of a bullet body of a non-ductile metallic substance and of circular cylindrical form having tow ends and a ductile drive band closely encircling said bullet body at a location between said two ends.

A bullet comprised of a bullet body and a ductile drive band closely encircling said bullet body, wherein said drive band comprises a ridge and a groove about its circumference, and said ridge is located ahead of said groove and projects radially outwardly beyond an external peripheral surface of said body.

A gun comprising a magazine for holding a plurality of projectiles, a body, a trigger mechanism for triggering the firing of a projectile from said magazine, a barrel for receiving and ejecting the fired projectile, a traversing mechanism for advancing said magazine stepwise and unidirectionally through a transverse aperture through said body, said magazine being arranged to be loaded with said projectiles from the front of said magazine into a plurality of chambers each having an opening at said front of said magazine, a propellant-material-receiving, rearward portion and a projectile-receiving, forward portion, the arrangement being such that, if a double charge of propellant material is loaded in said chamber, a projectile then loaded in said chamber would extend beyond said front of said magazine so that said magazine would be prevented from advancing through said transverse aperture.

In combination:

• a gun comprising a magazine for holding a plurality of projectiles, a body, a trigger mechanism for triggering the firing of a projectile from said magazine, a barrel for receiving and ejecting the fired projectile, a traversing mechanism for advancing said magazine stepwise and unidirectionally through a transverse aperture through said body, said magazine being arranged to be loaded with said projectiles from the front of said magazine into a plurality of chambers each having an opening at said front of said magazine, a propellant-material-receiving, rearward portion and a projectile-receiving, forward portion,
• propellant material in said rearward portion, and
• a cylindrical bullet in said forward portion.

A gun comprising a magazine for holding a plurality of projectiles, a body, guiding surface portions of said body and serving to guide linearly advance of said magazine through a transverse aperture through said body, a trigger mechanism for triggering the firing of a projectile from said magazine, a barrel for receiving and ejecting the fired projectile, a traversing mechanism for advancing said magazine stepwise and unidirectionally through said transverse aperture, said magazine being arranged to be loaded with said projectiles from the front of said magazine.
