Note - Per Mallory - The change in chamber dimensions occurred at around serial number 213,000.

If Mallory was correct, Model 1898 Krags (below that number), and model 1896 & model 1892 Krags, may have more liberally dimension-ed chambers.

FWIW - (Re-barreled Krags can totally different. I use to have a model 1898 'cut-down', that was put together by Sedgley. The replacement barrel was made from a (1905 dated) 1903 Springfield barrel. The tight chamber would accept factory ammo and my F.L. resized cases. It would not accept a 'fired case' from any of my other Krags).
