Primer compositions PA-101 basic lead styphnate barium nitrate antimony sulfidetetracenealuminum and PA-101D dichromated Al added proved to have low impulse and gas volume values. These are two characteristics of a primer composition that consistently initiate delay compositions in an obturated system. The primer compositions were stable when subjected to storage at extreme temperatures over a period as long as one year. M42 Primers when loaded with 20 mg of either PA-101 or PA-101D and consolidated at 6,000 psi will consistently initiate Type II Zr-Ni alloy delay compositions. The PA-101D dichromated composition appears to be equivalent to plain PA-101 and in addition has better flow properties.
