Abstract

A projectile of a predetermined geometrical configuration for small arms ammunition which comprises a solid monolithic body made of a copper alloy of approximately 61.5% of copper, approximately 35% of zinc, approximately 3% of lead and approximately 0.5% of tin.

Claims

1. A projectile for small arms ammunition comprising:

a projectile body made of a homogeneous solid material,

said material comprising a copper alloy consisting of approximately 61.5% of copper, approximately 35% of zinc, approximately 3% of lead and approximately 0.5% of tin.

2. The projectile set forth in claim 1 wherein:

the amount of said copper, zinc, lead and tin can vary 20-40 percent.

3. The projectile set forth in claim 1 wherein:

said projectile body has a tensile strength of approximately 65,000 pounds per square inch, a yield strength of approximately 57,000 pounds per square inch for a 0.2% offset.

4. The projectile set forth in claim 1 wherein:

the outer configuration of said projectile body comprises cylindrical guide portions extending between its ends of a diameter as large as the maximum inside diameter of the barrel of an associated weapon through which the projectile is intended to travel, and a rounded tip forming the nose of the projectile.

5. The projectile set forth in claim 4 wherein:

said body comprises a base, cylindrical walls and a nose,

said walls being formed substantially perpendicular to said base of said projectile.

6. The projectile set forth in claim 5 wherein:

said nose comprises a hemispherical configuration.

7. The projectile set forth in claim 6 wherein:

said alloy comprises approximately 61.5% of copper, approximately 35% of zinc, approximately 3% of lead and approximately 0.5% of tin.

8. The projectile set forth in claim 7 wherein:

said projectile body has a tensile strength of approximately 65,000 pounds per square inch, a yield strength of approximately 57,000 pounds per square inch for 0.2% offset.
