What is charge interference and how does it affect performance?
Charge interference occurs when the blast effect from one charge deflects or bends the jet stream from its meighbouring charge. Effect is more pronounced at higher shot density. In a bottom fired gun, the jet stream will bend upwards with increasing intensity. This will therefore cause the effective perforating tunnel to shorten and become less efficient. To help alleviate this problem, XHV detcord should be used on all carriers shot at 17 SPM or greater.
