The carbine has a steel butt plate, with an oiler compartment.
This was considered a big plus when it was adopted, but the later Mauser method of using stripper clips to load the magazine made it less of an issue. It consists of a magazine that holds 5 cartridges, but a gate can be opened to allow “topping-off” of a partially emptied magazine with loose rounds. The rifle Ted got is actually a Krag Carbine, with a barrel slightly shorter than the Krag Rifle. But it was out-classed by the Spanish Mauser in the Spanish-American War, and the War Department decided to replace it with the 1903 Springfield. Many writers have spoken of the “buttery smooth” Krag bolt action. It has a reputation of being one of the smoothest bolt actions ever built, and deservedly so. It was used in the Philippine War and a song of that time even spoke of the rifle. The military only used this rifle for about 11 years, from 1892 to 1903, giving it the dubious distinction of having the shortest life span of any US military rifle. It has a rim, but an unusual “rebated rim”, as compared to other rimmed cartridges, such as this. It made just less than 2,000 fps, which was kind of hot in that day. 30-40 Krag round, which was originally a smokeless cartridge that shot a 220 grain round nose bullet over 40 grains of a smokeless powder. But in the US, it was usually shortened to just “the Krag”. It was designated the Krag-Jorgensen rifle. The rifle that was selected was based on the Norwegian design by two men named Krag and Jorgensen. 30-40 Krag was adopted by the US military in 1894 as the military’s first smokeless powder cartridge. It was dirty, but I cleaned it up for him and under that grime was one of the cleanest Krags I’ve ever seen, with a “Perfect” bore. Ted found an example at a pawn shop and got it for a very reasonable price. But the next best thing happened… My buddy Ted bought one that I can shoot.
