Shotshell with shot pellets having multiple shapes

1. A shotshell comprising:

a casing defining an internal chamber;

a plurality of first shot pellets within the internal chamber, said first shot pellets comprising a first shape; and

a plurality of second shot pellets within the internal chamber, said second shot pellets comprising a second shape that is different from the first shape, said second shape comprising a raised ridge and flat opposed end portions, a cross-section taken through said raised ridge having a circular shape, said second shape being symmetric across said cross-section.

2. The shotshell of claim 1 , wherein a drag coefficient of a second shot pellet is greater than a drag coefficient of a first shot pellet.

3. The shotshell of claim 1 , wherein said cross-section defines a largest diameter of said second shape.

4. The shotshell of claim 3 , wherein said first shot pellets are spherical.

5. The shotshell of claim 1 , wherein said first shot pellets are non-spherical.

6. The shotshell of claim 1 , wherein said second shot pellets comprise a sharp edge.

7. The shotshell of claim 1 , wherein said second shot pellets comprise a cylindrical portion.

8. The shotshell of claim 1 , wherein said raised ridge comprises first and second flat portions.

9. The shotshell of claim 1 , wherein said second shot pellets are asymmetric across at least one axis.

10. The shotshell of claim 1 , wherein said first shot pellets comprise 60% of the shot load and said second shot pellets comprise 40% of the shot load.

11. The shotshell of claim 1 , wherein said first shot pellets are grouped toward the front of the internal chamber and said second shot pellets are grouped toward the rear of the internal chamber.

12. The shotshell of claim 1 , wherein said first shot pellets are grouped toward the rear of the internal chamber and said second shot pellets are grouped toward the front of the internal chamber.

13. The shotshell of claim 1 , wherein said first and second shot pellets are evenly distributed throughout the internal chamber.

14. The shotshell of claim 1 , wherein said first and second shot pellets are non-toxic.

15. The shotshell of claim 1 , wherein said first and second shot pellets comprise steel.

16. The shotshell of claim 1 , comprising layers of first shot pellets and second shot pellets.

17. The shotshell of claim 1 , wherein the first shot pellets and second shot pellets are commingled within said internal chamber.

18. The shotshell of claim 1 , wherein the first shot pellets are radially separated from the second shot pellets.

19. The shotshell of claim 1 , wherein said second shot pellets comprise a single raised ridge.

20. The shotshell of claim 1 , wherein said raised ridge consists of first and second flat portions.

21. The shotshell of claim 1 , wherein said second shot pellets spread more than said first shot pellets when the shotshell is fired.

22. A shotshell comprising:

a casing defining an internal chamber;

a plurality of first shot pellets within the internal chamber, said first shot pellets comprising a first shape; and

a plurality of second shot pellets within the internal chamber, each second shot pellet comprising a non-spherical shape having a raised ridge and flat opposed end portions, wherein a cross-section of said second shot pellet taken through said raised ridge is circular.
