Two tests with the same test setup and with the same nominal type of acceptor charge will be described which give in both cases an initiation after a build‐up distance of around 45 mm. But in one case a retonation started, and in the other case a second initiation centre was observed after an additional delay time of 6.4 μs. In the already perforated charge segment the detonation wave was running around an internal core and was interacting in a Dautriche event on the observed front side. Very similar results have already been observed in a very early study of jet initiation tests. Both test results are described in detail, their analyses are presented and compared to the results of the observations, some decades ago.
