Sounds like the military solution, then. Alan Jones said CCI reformulated their magnum primers to optimize them for spherical propellants in 1989, but they apparently get the heat up using barium nitrate, as their MSDS has no PETN. Barium oxidizers do burn hot. I remember they were necessary to get thermit to ignite consistently when I was playing with that stuff in the 60's.
