DEVELOPMENT AND MANUFACTURE OF SPECIAL CALIBER .30 ELECTRIC PRIMERS
Abstract
Efforts were devoted to reduce the amount and/or conductivity of the solid residue from the caliber .30 electric primer used in the T-2 switch and to increase the reliability of the primer. Current work has shown that the mixture (XP403) which resulted in the least amount of solid residue is much too powerful; even at the lowest weight that can be charged in the primer the switch case may be cracked or the electrode assembly be pushed out of the switch case. Mixtures with intermediate amounts of residue (XP401) seem more promising in this respect but even then the electrode assembly may be partially separated from the switch case if the crimp is comparatively weak.
