Does anybody know if the Army ever tried spitzer bullets in the .30-40 ctg.?
There were a lot of experimentation with a 30-40 Krag with different bullets.
One that they did quite a bit work with was a hollow bullet with a sabot. These tubular bullets were invented by Prof. F. W. Hebler of Switzerland.
In 1894 they experimented with the Farley sharp pointed bullet that weighed 131 grains but not adapted.
The early 30-03's used a round nose bullet until the Spitzer type was adopted in 1906.
