This report describes the design and development testing of a stab initiated delay primer for ordnance application. Its initiation sensitivity is .75 in-oz, delay time is nominally 10 ms, output is 27 mg of RD 1333, and its overall size is .16 diameter by .30 long. 650 primers were built and results of shock, temperature, and confinement variable tests on 500 units are presented. Mean function time ranged from about 9 to 12 ms over the temp range of -65F to 160F and the sigma ranged from about 1 to 2 ms. The final design is rugged, reliable, and simple to produce. Author
