Abstract

A slug assembly for a shotgun shotshell, having a slug which has a circular largest diameter portion, and which has at least one cylindroid portion consisting of inclined generatrices, a sleeve like spacer made of a plurality of split spacer elements coaxially surrounding the slug. The spacer has inner portions which come into close contact with the cylindroid portion of the slug. The slug assembly also has a disc like stabilizer between the wad and the slug, connected to the slug by means of male and female connectors. A front surface of the stabilizer comes into close contact with the rear end of the spacer.

Claims

1. A slug assembly for a shotgun shotshell having a case with a primer, a powder in the case, and at least one wad in the case adjacent to the slug assembly, said case being crimped at its front open end, said slug assembly comprising:

a slug having a circular largest diameter portion coaxial to the axis of the slug, and at least one cylindroid portion at the rear of the largest diameter portion having a radius from the axis of the slug decreasing toward the rearward direction of the shotshell;

a spacer which is made of a plurality of split spacer elements so as to define a sleeve surrounding the slug in a direction coaxial to the slug when the spacer surrounding the slug is inserted in the case, each of said spacer elements defining a space surrounding the slug, said spacer being provided, on its inner surface, with portions which come into close contact with the cylindroid portion of the slug; and

a stabilizer having a disc body between the wad and the slug, secured to the slug by means of male and female connectors, said stabilizer having a front surface which comes into close contact with the rear end of the spacer, said stabilizer having a diameter larger than said largest diameter portion of the slug.

2. A slug assembly according to claim 1, wherein said spacer elements are spaced from one another around the slug at a predetermined gap.

3. A slug assembly according to claim 1, wherein said slug is made of a plurality of elements.

4. A slug assembly according to claim 3, wherein the plurality of elements of the slug are made of different materials.
