I think the Krag was quite similiar to other rifles of the period in that it was a magazine rifle loaded one round at a time. The thinking at the time was that was good enough. Anything else would be wasting ammunition. It took a war to demonstrate that was not a good idea. Our war was the Spanish-American War, the British war was the Boer War. The other side in both was armed with Mausers that had charger loading. So after the war, you just had to have charger loading or you were hopelessly old-fashioned.
But the old ways died hard. The 1903 Springfield had a magazine cutoff and so did some of the Lee-Enfields. Even Jeff Cooper believed his ideal Scout Rifle should have a provision for a magazine cutoff. And you thought he was progressive.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
