After reading the comments, I found that many book friends believe that the accuracy of the Mosin Nagant is higher than that of the German K98K. This is a very interesting topic. I will say a few words here. What I say is not necessarily correct. Let’s just discuss the matter.
I believe book friends will think so. Most of them have seen the overwhelming number of posts on the Internet saying that the accuracy of Mosin Nagant is higher than k98k.
I have seen posts like this before, but they were obviously rumors, so I clicked the cross in the upper right corner.
Online posts believe that there are roughly three reasons why Mosin Nagant is more accurate:
1: The k98k bullet is larger, 7.92mm, and the warhead is heavier, so the accuracy is of course worse.
This view is extremely wrong and can even be said to be contrary to the facts.
It is true that the warhead of a large caliber is heavy, but at the same time its charge is doubled to provide it with a higher muzzle velocity... A very important indicator of accuracy is actually the muzzle velocity, which will be explained later.
You can refer to Barrett. Its warhead weighs 45.8 grams and has a caliber of 12.7mm. According to this theory, its accuracy should be far inferior to that of the Mosin Nagant, but the fact is exactly the opposite.
Two: k98k has large recoil, so its accuracy is poor.
This is also extremely wrong and even contrary to the facts.
The recoil is due to the large amount of powder charge. The large amount of powder charge means higher muzzle velocity, and higher muzzle velocity means higher accuracy... But ordinary people's thinking is that recoil means vibration, so the accuracy is lower.
.
You can also refer to the Barrett. Its recoil is not low. If this reason is true, the accuracy of the Barrett should be lower than that of the Mosin Nagant.
Three: The k98k has a short barrel and the Mosin Nagant has a long barrel, so the latter has better accuracy.
This is the only reason that makes some sense, because a long barrel means that it can run a longer distance in the barrel to obtain more rotational force in the rifling, so it can spin faster and fly more stably.
But this is not the decisive factor, it can only be said to be a secondary factor, and sometimes it may even affect the accuracy.
Investigating the reason, we should talk about the issues of accuracy and muzzle velocity.
A characteristic of bullets flying in the air is that they are very stable when flying at a speed higher than the speed of sound. Once the speed drops below the speed of sound, the deflection will increase exponentially.
Therefore, there is a saying that "Look at the bullet before looking at the gun." For accuracy, it is not the gun that determines the accuracy, because the manufacturing process, rifling, etc. of the gun are actually similar, such as k98k and Mosin Nagant... In fact, the gun is not the same.
The manufacturing process of Shinagan is much rougher than that of k98k.
The charge of the bullet and the friction of the rifling determine the muzzle velocity of the bullet the moment it exits the barrel.
This muzzle velocity will gradually decrease due to the resistance of the air. When it decreases to the speed of sound, it is basically its range, that is, its accuracy.
Of course, there will be some subtle differences between different guns. For example, the roughness of the AK47 means that due to the vibration of the gun itself, the range is lower than the distance where the bullet drops to the speed of sound. However, because the M16 is well made, the bullet still has a certain distance when it drops to the speed of sound.
accuracy, so the range is slightly longer.
If you know this, it is easy to understand: an important data for accuracy is muzzle velocity. Any article that discusses accuracy without muzzle velocity is a hooligan. You can click the cross in the upper right corner to turn it off...
Therefore, it does not mean that the longer the barrel, the higher the accuracy, because a long barrel will cause the bullet to lose kinetic energy due to excessive friction in the rifling and reduce the muzzle velocity.
Then, brothers only need to compare the muzzle velocities of the two to know the accuracy.
Another note: In 1942, the Soviet Army was still equipped with many Model 1891 Mosin Nagants. This rifle was discontinued in 1926. In other words, the latest one has been in the warehouse for 16 years. It is difficult to imagine that the accuracy of this rifle will be
Higher than the newly produced k98k.
The improved model 1891/30 was put into production in 1930 and was not fully equipped until 1943.
