And to add to Jerry's note, Krags were used for a long time in the 'teens and '20s and '30s by Caribbean regimes set up by the US military in Haiti, Nicaragua, and other nasty little hotspots. They also were used a fair amount by Mexican revolutionaries in the 1910-29 festivities next door, as were Winchester 1895s in that caliber. Not as much as .30-30 "Oinches" but I see them in pix from that era a fair amount.
What I really like is the single shot rifles made on Krag actions like my no-name .22 Hornet.... Most of my experience with the .30-40 is in 'walls and Ruger #1s. It is a very under-rated round.
