Abstract

A round for a magnetically chambered air gun has a magnetically influenced portion and a non-magnetically responsive portion, as well as an exterior shell and an interior. The interior may be hollow, solid, or filled with liquid. Any part of the invention may be the magnetically responsive portion: the shell, the interior, the solid or liquid core and so on. The round may advantageously be spherical, and may include an actual magnet itself as opposed to merely being magnetically responsive. Magnetic materials may be impregnated into a non-magnetic portion such as a plastic shell. The shell may be of multiple part construction with a snap together design.

Claims (34)

1. A round of ammunition comprising:

a spherical body, the body comprising a first body part and a second body part;

the first body part being a core;

the second body part surrounding the core and being a shell about the core, the second body part having an interior void into which the core is disposed;

the second body part being made of two constituent materials, a first structural material which is non-magnetic and a second magnetically responsive material dispersed within the first structural material; and

a magnet disposed within a material of the first body part.

2. The round of ammunition of claim 1 , the first structural material further comprising: a polymer.

3. The round of ammunition of claim 2 , the first structural material polymer further comprising: a shock absorbing polymer.

4. The round of ammunition of claim 2 , wherein the second magnetically responsive material further comprises: particles of metal.

5. The round of ammunition of claim 4 , wherein the particles of metal further comprise: iron filings.

6. The round of ammunition of claim 2 , wherein the core further comprises: a gas.

7. The round of ammunition of claim 2 , wherein the core further comprises: a metal.

8. The round of ammunition of claim 1 , wherein the second body part is comprised of a plurality of sections, the sections having fastening means by which the sections are fastened together about the core.

9. The round of ammunition of claim 8 , the fastening means further comprising:

on a first one of the sections, a plurality of tabs, each tab having thereon at least one catch,

on a second one of the sections, at least one detent, the detent dimensioned and configured to accept the catch into mechanical engagement, whereby the two sections are fastened together.

10. The round of ammunition of claim 8 , wherein the shell further comprises:

a plurality of fragmentation grooves whereby the shell may more easily fragment upon impact;

and further whereby the shell may absorb energy by means of fragmenting upon impact.

11. The round of ammunition of claim 1 , wherein the first structural material is biodegradable.

12. The round of ammunition of claim 11 , the first structural material further comprising one member selected from the group consisting of: paper, cellulose, wood fiber, saw dust, powder, polymer, recycled material, compressed materials, and combinations thereof.

13. The round of ammunition of claim 11 , wherein the second magnetically responsive material comprises one member selected from the group consisting of: iron filings, metal particles, recycled material, compressed materials, and combinations thereof.

14. A round of ammunition comprising:

a spherical body, the body comprising a first body part and a second body part;

the first body part being a core;

the second body part surrounding the core and being a mantle about the core, the second body part having an interior void into which the core is disposed;

the second body part being made at least in part of a structural material which is non-magnetic;

the second body part being made at least in part of a material which is magnetically responsive; and

a magnet disposed within a material of the first body part.

15. The round of ammunition of claim 14 , the magnet further comprising:

a rare earth magnet.

16. The round of ammunition of claim 15 , wherein the rare earth further comprises:

Neodymium.

17. The round of ammunition of claim 14 , wherein the material of the second body part further comprises: iron filings.
