Abstract

Various items of apparatus are disclosed including: 1) a gun (2) having a body (3), a trigger mechanism (4-21), a barrel (34), a magazine for holding a plurality of projectiles, and a traversing mechanism (44) for advancing the magazine stepwise and unidirectionally through a transverse aperture (30) through the body (3), 2) a device for dosing an exact amount of propellant material into the magazine, 3) a device for inserting a primer into the magazine, 4) a device for removing a used primer from the magazine and/or seating a projectile in the magazine, and (5) bullets of which one is particularly designed for the user with the gun (2).

Claims

1-46. -46. (canceled)

47. 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.

48. A bullet according to claim 47, wherein the maximum external diameter of said band is greater than the maximum external diameter of said body.

49. A bullet according to claim 47, 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.

50. A bullet according to claim 49, wherein the maximum external diameter of said band is greater than the maximum external diameter of said body and is a maximum external diameter of said ridge.

51. A bullet according to claim 47, wherein said drive band comprises ridges and grooves about its circumference, and each ridge is located immediately ahead of an associated groove and projects radially outwardly beyond an external peripheral surface of said body.

52. 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.

53. A bullet according to claim 52, wherein the maximum external diameter of said band is greater than the maximum external diameter of said body and is a maximum external diameter of said ridge.

54. 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.

55. A gun according to claim 54, wherein a bullet-seating shoulder defines the boundary between said rearward portion and said forward portion.

56. A gun according to claim 54, wherein each chamber includes a rearwardly open sub-chamber for loading with a primer, and a short bore interconnecting said sub-chamber and said rearward portion.

57. A gun according to claim 54, wherein said magazine is a linearly displaceable, load block.

58. A gun according to claim 54, wherein said magazine is a rotary cylinder.

59. 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.

60. A gun according to claim 59, wherein a bullet-seating shoulder defines the boundary between said rearward portion and said forward portion.

61. A gun according to claim 59, wherein each chamber includes a rearwardly open sub-chamber for loading with a primer, and a short bore interconnecting said sub-chamber and said rearward portion.

62. A gun according to claim 59, wherein said magazine is a linearly displaceable, load block.

63. A gun according to claim 59, wherein said magazine is a rotary cylinder.

64. 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.
