Abstract From the Canadian patent
Disclosed is a small-bore projectile (100) comprising an outer jacket (5) made of tombac, a hard core (4) made of hardened steel and a hollow jacket core , (8) that is also made of tombac. The kinetic energy is substantially transmitted to the hard core (4) when a target (Z) is hit such that said hard core (4) penetrates the target (Z). The ductile jacket (5) is supported by the jacket core (8) that is located on the inside and mushrooms up into a deformed jacket (5') without fragmenting. The inventive projectile (100) is provided with a good flying behavior and a great final ballistic performance and can be produced in an entirely lead-free manner.

Why it's free to use
- Filed May 9, 2005 and granted January 13, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 9, 2025.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
