Abstract

This invention relates to priming compositions for ammunitions containing manganese dioxide as oxidizer agent in the primer mix, and to the rimfire cartridge containing dinol, manganese dioxide, tetrazene and glass.

Claims

1. A priming composition for use in rimfire cartridges which consists essentially of a lead-free, non-toxic, non-corrosive mixture of dinol, manganese dioxide, tetrazene and glass.

2. The composition of claim 1 in which the weight percentage of the ingredients in the composition is within the following ranges:

space="preserve" listing-type="equation">dinol;

25%-40%

space="preserve" listing-type="equation">manganese dioxide;

10%-40%

space="preserve" listing-type="equation">tetrazene;

10%-40%

space="preserve" listing-type="equation">glass;

10%-30%

3. The composition of claim 2 wherein the dinol has a particle size within the range of from about 30 microns up to about 250 microns.

4. The composition of claim 2 wherein the combined weight percentage of dinol and tetrazene in the composition is within the range of from about 40% up to about 60%.

5. The composition of claim 2 wherein the weight percentage of manganese dioxide in the mix is within the range of from about 15% to about 25%.

6. The composition of claim 2 wherein the weight percentage of dinol in the mix is within the range of from about 25% to about 35%.

7. A non-corrosive ammunition priming mix which contains manganese dioxide as an oxidizer agent.
