Many of those who are interested in weapons are well aware that special recesses are often made in butts for placing a pencil case with useful tools for maintaining weapons. So the question arises: why in the entire history of firearms, none of the designers suggested using the internal space of the butt as a magazine for cartridges?
In fact, the idea of placing a magazine with cartridges in the butt of a rifle was first voiced back in the 19th century. The pioneer in this field is the American Christopher Spencer, who patented his carbine and rifle with a magazine butt in 1860. At first, Spencer suggested hiding only one tube with cartridges in the store. And as you might guess, then the designers hit "breaking bad". One magazine tube in the butt was immediately followed by two, and then three with a rather cunning ammunition supply system. In particular, such a rifle was proposed in 1885 by the German designer Ferdinand Mannlicher. And then there were Evans and Wilson rifles in which there were 5 sections of cartridges in the butt at all!
The creativity of the designers was wonderful. However, creativity-creativity, but stores in butts had several very serious shortcomings. Firstly, all such stores suffered from bolt failure, which could happen if the next cartridge for some reason did not come out or even be late. Secondly, in the event of a misfire, there is a high probability that the remaining cartridge will hit the bullet of the next serving one. This problem is treated by the power draft of the store. However, such actions are fraught with an explosion of ammunition (shot inside the store). Thirdly, such a store can be closed only with the shutter open and before the trigger is pulled. Violation of this rule is fraught with damage to both the handle and the entire trigger mechanism.

In other words, the design of the stores in the butt turned out to be extremely unreliable. Until the 20th century, designers in Europe and the United States struggled to solve the problems they discovered. The greatest success in this field was achieved by the already mentioned Ferdinand Mannlicher, who proposed an oval tube for cartridges, which prevented the primer from being pricked and thereby solved several fundamental problems at once problems. However, the trouble was that each subsequent attempt to "cure" a promising design turned into something that is not loved so much either in the army or in production - a complication. As a result, if any Lebel rifle was used until the 1940s, then magazine stocks did not even go into mass production.
