1. A method of making a percussion primer, the method comprising:
- a) providing at least one water wet explosive;
b) adding a dual buffer system to said at least one water wet explosive;
c) combining at least one nano-size non-coated fuel particle having natural surface oxides thereon with said at least one water wet explosive and said dual buffer system to form a first mixture; and
d) combining at least one oxidizer with said at least one water wet explosive or with said first mixture.
