Early experimental loadings were composed of a 220-grain FMJ RN bullet and 40 grains of blackpowder, but that was soon changed to smokeless powder. In 1893 Winchester began offering the High Wall single-shot rifle chambered for the .30-40 Krag and, as such, became the first commercial U.S. arms maker to offer a small-bore smokeless-powder sporting cartridge. That was nearly two years before the smokeless-powder .30-30 Winchester.
Primer: CCI 200
Max Case Length: 2.314 in.
Trim Length: 2.304 in.
OAL Max: 3.089 in.
The .30-40 Krag served the country well for a decade, and when military-surplus rifles became available to the public, the cartridge proved to be very successful with hunters. With heavy bullets, the Krag can be effective on elk and moose, and loaded with a modern 180-grain bullet, the Krag is an excellent deer cartridge out to 250 yards.
Handloading the Krag can be tricky due to relatively inconsistent loading data. Special attention must be paid to working up maximum loads, especially in vintage Krag rifles. But as this project demonstrates, the results of shooting a modern rifle can be very pleasing.
The industry Maximum Average Pressure for the .30-40 Krag is 40,000 CUP.
