I have an 1896 Krag infantry rifle in original configuration, and in excellent condition. Surprisingly has a bore that mikes at .308". It's good shooter with cast boolits, except that the 1896 sights have no windage adjustments. I've never fired jacketed bullets in it.
I have only a few dozen .30-40 cases, so lots of my reloading is done with resized .303 cases, which seem to work just fine.
