The Testing Device of Cartridge's Primer and Testing Method

The testing device for testing the performance of cartridge's primer was designe d. The performance of press-loading small primer conld be measured, and the sma ll primer's is fixed ammunition. The results of testing and analysis show that t he performance of cartridge's primer vary regularly with stored time, and the ch anges make an obvious effect on the interior ballistic performance. A new way is suggested for the study of reliability on the stored ammunition and the analysi s of accident.
