I noted this on ebay. It was interesting to note that Sedgley thought the Krag action strong enough for the 250-3000. Pretty impressive with an 87gr bullet at 2700fps. That'd be a fairly mild loading, even milder than the start loads shown for the cartridge on Hodgdon's website. Makes my wildcat rimmed 6mm Niemiller look a little more doable. I recall reading somewhere that Sedgley would only work on Krag receivers that would take a file.
