The most popular paid article we have recently promoted: Take the other house, and look back to the relocation of the gate: My mind's 95 rifle (1)
Hello everyone, this is a question from an old man. I want me to evaluate the 7.62×25mm pistol bullet, which is the bullet used by TT33/54 pistol, Type 54, and Type 379 submachine gun .
Frankly speaking, the evaluation of gun bullets involves a lot of different knowledge and perspectives, and I am not professional. So I still start from the areas I know quite well and try to comment on this bullet from a unique perspective.
My point is: This is a pistol bullet that doesn’t look like a pistol bullet.
In the era when 7.62×25mm was born, more pistol bullets, such as 9×19mm bullets, used a straight cylindrical shell, which is typical of "bucket body", has a chubby appearance and a relatively fat bullet head. The 7.62×25mm uses a bottle-shaped shell, which has a "skinny" appearance and a relatively thin warhead. In terms of parameters, the 7.62×25mm warhead is lighter, but the initial velocity is relatively high. On the contrary, 9×19mm has a heavier warhead and a slower initial velocity.
△ 7.62×25mm (first left) and 9×19mm (third left), the second left is 9×18mm Makarov , and the fourth left is .45ACP. 7.62×25mm is really long.
Many articles say that the core reason for the elimination of 7.62×25mm is that it has low lethality, but its penetration (throughput) power is too strong and it is not suitable for use as a pistol, especially police pistol . I personally do not agree with this view.
The reason is also very simple. In terms of lethality, 7.62×25mm is definitely one at a time. I have never heard of complaints about the lethality of this bullet. The only similar statement I have heard is: "The 7.62×25mm warhead movement is too stable, affecting the release after invading the target." The original meaning of this sentence is that if the optimization is better, the lethality of 7.62×25mm is greater, but it is by no means that the lethality of 7.62×25mm is not enough at this stage.
As for the statement that "7.62×25mm is too penetrating" is actually even more nonsensical. Military pistols never mind strong penetration. What's more, the penetration power of the gun bullet is hugely related to the warhead structure. If you replace a pure lead-core bullet with 7.62×25mm, even if the penetration power is larger than 9×19mm, it will not be "scary" - think about it, 5.7×28mm bullet has a penetration power that is higher than 7.62×25mm, so you can still change to a warhead mixed-use civilian market. Why can't 7.62×25mm do this?
△ 5.7×28mm bullet has superior penetration, but it can also be launched for civilian versions, such as the SS197SR in the picture. The bullet tip is made of plastic
. Therefore, the core reason why 7.62×25mm is gradually eliminated is not that it has low lethality, nor that it has too strong penetration, but that it has other reasons. In my opinion, this reason is actually very simple: it is too long to play.
Yes, the answer is length. The total length of 7.62×25mm reaches 35mm, compared with the total length of 9×19mm bullets is only 29.7mm. The pistol bullet is for pistols. This sentence sounds nonsense, but in fact, it is interesting to think about it carefully.
We know that 7.62×25mm comes from the Germans' 7.63×25mm, and who is the 7.63×25mm for whom?
is for C96. What is the difference between
C96 and modern pistols? The magazine of
C96 is not in the grip.
△ C96 and M1911, C96 has a 7.63×25mm bullet length larger than M1911 .45ACP
. Because of this, C96 does not require much bullet length. Modern pistol magazines are all in the grip. If you want to stuff such a long pistol bullet into the grip, it is easy to make the grip of the pistol bigger. If you put on a double-row magazine, it will be even bigger. For example, I have seen a 7.62×25mm caliber domestic P22X/NP2. The grip is really Quentin's famous scene: it's so big.
△ 7.62×25mm caliber NP22, the grip is really big
In addition, every country often has at least two pistols, one for combat and the other for self-defense. Although using 7.62×25mm for combat pistols will cause a large grip, it is acceptable. But the small self-defense pistol really can't fit 7.62×25mm.Still the same sentence, it's so big.
So, after the war, the Russians might have had long ptsd and created a 9×18mm bullet. This shell is only 1mm shorter than 9×19mm, but the actual length of the shell is much shorter, much shorter than 7.62×25mm. The Russians' small self-defense pistol (Makarov) and large combat pistol (APS) are both used.
, and our country has retained the 7.62×25mm and 54 types, and has also developed the 77 and 64 types that use 7.62×17mm bullets. A special projectile was developed for a small self-defense pistol. After comprehensive consideration, the cost is actually not low.
In comparison, although it is a bit reluctant to stuff a 9×19mm into a small self-defense pistol, it is not unusable, such as the P365 we introduced earlier. If you think the P365 is too new, you can refer to the P7 in Germany.
△ The size of P7 is much larger than PPK, but it is not too big itself. It can be used as a self-defense pistol
In short, a pistol is a second-line weapon, and it is best to use a bullet instead of a large pistol and a small pistol. It is only a matter of simplifying the type of bomb, but it is inevitable. We were the same later. The 5.8×21mm bullet (also shorter than 7.62×25mm) is used for both the large-sized 92 type and the small-sized 11 type. From this point of view, 7.62×25mm is really hopeless.
△ Type 11 pistol serves as a small self-defense pistol
To put it bluntly, I think the "hard indicator" that stuck 7.62×25mm is not the lethality and penetration that everyone imagines, but the length that many people have ignored. It's like you want to recognize Xiaoqin Lao Wang as your master, but Xiaoqin Lao Wang refuses to accept you. It’s not because you are not working hard or smart enough, it’s simply because Lao Wang doesn’t accept male disciples. The final kill is out of help.
△ Among the three types of bullets, .45, .40 and 10mm, the largest length is .45ACP, the length is 32.4mm, and it is not as long as 7.62×25mm. .40 and 10mm optimize the warhead shape, trying to reduce the length of the bullet
So, is there no hope at all 7.62×25mm? Neither. The PDW concept began to prevail in the late 1980s. The bullets used in PDW, whether they are 5.7 or 4.6, are bottle-shaped and have a very large bullet length. The reason why this generation of bullets is very long is that the PDW bullet is dedicated to submachine gun (at least that was the case back then). Using PDW bullets to develop pistols is just icing on the cake, not a hard requirement. The PDW's bullet is no longer forced into the pistol grip.
In the article "My Gun Story 3-Type 54 Pistol", when a junior brother and I were having hot pot, we discussed the possibility of changing the 7.62×25mm with a lighter, sharper and thinner warhead, and the initial velocity was increased to 700+ as a PDW bullet. The conclusion seems to be nothing impossible, after all, it already has a speed of 500 on the submachine gun. The magic modification 7.62×25mm is definitely not as professional as the specially designed PDW, but isn't much stronger than the small-diameter but not high-speed "pseudo PDW bullet" of 5.8×21mm?
△ From left to right, we are 5.7×28mm of Belgium , 4.6×30mm of Germany, and 5.8×21mm of my country. Our bullet length is the shortest and the power is the smallest. But strictly speaking, my country's 5.8×21mm is not a PDW bullet, but a pistol bullet. This is also the reason why it is so powerful, because it is not a chicken
Unfortunately, 7.62×25mm did not last until the PDW day.
