Seems way too fast even for a 30+/- inch barrel in acceptable pressures for the Krag action. One of our Norwegian members might weigh in but if I remember correctly, the Krag for a long time (maybe still?) was not normally used for the large animal class in Norway due to limitations of joules in factory loads (which were held to lower pressures amenable to the Krag action). Maybe somebody can weigh in and clarify?
