In extreme cases, the beginning masses produced small delayed firings — possibly during the range of 20 to 40 milliseconds but detectible to a qualified ballistician. Switching that propellant to some Magnum primer smoothed out the overall performance over the practical range of charge weights and fully removed the delays. https://emiliouzzxu.ageeksblog.com/30718708/rumored-buzz-on-cci-250
