Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed July 5 1918. Serial No. 243,441.

The prime object of my invention is to provide a cartridge having a composite projectile charge in which the core or central portion of the charge will be composed of larger shot to constitute the effective charge at the maximum distance, together with a convoying surrounding mass of smalle shot which serves to retard the scattering of the larger shot during a part of the trajectory.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a longitudinal section of a cartridge having a projectile charge made up in accordance with my invention;

Fig. 2 is a cross section on the line 2-2, Fig. 1.

In carrying out my invention in accordance with the illustrated example, a shell 10 is adapted to receive an explosive charge 11, the characte of the explosive charge and the details of the projectile charge not constituting any part of my invention. My improved projectile charge is made up of a central core of large shot 12 and a surrounding mass of smaller shot 13. In practice I have found it efi'ective to have the core of larger shot constituting approximately onethird of the total charge but the proportions may be varied within comparatively wide limits so that the core will constitute anywhere from one-eighth to three-quarters of the total charge.

By thus forming the projectile charge, I have found that the central core of larger shot; may be relied upon for elfectiveness at the maximum distance, the surrounding mass of smaller shot serving seemingly to retard the scattering of the core of larger shot during a portion of the trajectory, the novel loading being especially eiiective at from fifty to one hundred and twenty yards.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

A shot gun cartridge having a composite projectile charge of which a central core is composed of larger shot, there being a surrounding mass of smaller shot about said core.
