As a kind of matchlock gun, the bird spear is much more advanced than the firedoor gun with three large caliber short guns. As far as its lethality is concerned, the bird spear can penetrate the heavy armor within 100 steps, while the three-eye large-caliber short gun has basically no killing effect within 100 steps. You can only kill unarmed soldiers in 50 steps and kill the enemy in 30 steps. The accuracy of the bird spear also killed the three-eye large-caliber shotgun in an instant. If you want to hit the enemy accurately, you can only rely on faith. However, the three-eye large-caliber short gun was still the main fighting weapon of the Ming Dynasty for the following reasons. ?
Song Ying Xing's "Tiangong" introduced the production technology of chicken gizzards in detail. The reason why bird gizzard has such high performance is that its manufacturing technology is quite complicated and its natural price is very expensive. On the other hand, the three-eye large-caliber short gun is simple and rough, and can be made by simply casting iron or crude steel. The prices of the two are not comparable. A bird can be sold for 2~3 taels, and a large-caliber shotgun with three eyes can only be sold for 70 cents. At the end of the Ming dynasty, the central government was very short of money and could not afford such an expensive bird. In order to form a lasting strike force, bird hair must be constantly loaded and shot frequently, and the use of bird hair is very complicated, 1 1 step by step, which requires very high users. When the use is complicated, the shooting frequency will naturally decrease. However, when the cavalry charged quickly in the late Jin Dynasty, there was no time to give users enough time to replenish ammunition, which was the biggest disadvantage of the bird. Bird gizzards also need a very high proportion of gunpowder and pellets. Too much gunpowder is easy to explode, and the gunpowder is not lethal enough.
Three-eye large-caliber shotgun has certain advantages in these aspects, and it is very convenient to make and use, especially in hand-to-hand combat. You can kill your opponent quickly without aiming. The biggest problem is that the three-eye large-caliber shotgun is only a disposable weapon, and the three-eye large-caliber shotgun has no chance to replenish ammunition. The most important reason why the Ming army was not equipped with flying birds was the corruption and inefficiency of governments at all levels in the Ming Dynasty. When they make weapons and ammunition, they often cut corners, and even weapons such as armor and swords have to be forged, not to mention birds that need a certain production process, and the production process is even more uncertain.
