Lead-free projectile
First Claim
1. A small-bore projectile having an ogival or conical front region, a cylindrical central part and a conically extending tail region, further comprising:
- an outer jacket of a copper/zinc alloy, the jacket having a tip and enclosing a hollow space;
a hard core made of steel or a sintered material inserted into the hollow space towards the tip;
a jacket core made of a copper/zinc alloy having a front face attached with a form fit to a rear of the hard core and having a interior cylindrical hollow space open through the front face;
the jacket core front face being conical and positively resting against the hard core and sealing said hard core to the front face; and
the jacket core being in contact on a periphery over its entire length with at least the tail region of the jacket and being held with an interference fit.

Abstract
A small-bore projectile comprises a ductile outer jacket, a hard core, and a hollow jacket core. Kinetic energy of the projectile is substantially transmitted to the hard core when a target is hit such that said hard core penetrates the target. The outer jacket is supported by the jacket core that is located on the inside and mushrooms up into a deformed state upon impact without fragmenting. The projectile has good flying behavior and great final ballistic performance and can be produced in an entirely lead-free manner.

2. A small-bore projectile with an ogival or conical front region, a cylindrical central part and a conically extending tail region, further comprising:
-
an outer jacket made of a copper/zinc alloy, the jacket enclosing a hollow space;
the hollow space of the jacket solely containing a jacket core having an interior hollow space;
the hollow space of the jacket core comprising an aperture tapering towards a front face of the jacket core, the inner edge regions thereof being at least partially in contact with one another;
the jacket core being in contact on a periphery over its entire length with the jacket and being held with an interference fit.
