Chapter 14 Shooting Accuracy Test
Karl was dumbfounded, and it wasn't until Philip changed five magazines in a row and fired one hundred and eighty rounds with continuous fire that he recovered from his shock and clapped his palms vigorously and said, "Wonderful, really wonderful!" Philip, can you teach me this skill? ”
Philip laughed and said: "Mr. Karl, in fact, this is not a stunt, as long as a familiar gunner can do it, this is because the new assault rifle adopts the design of hanging up in the empty compartment, in short, the semi-automatic or automatic firearm automatically keeps the bolt open after firing the bullet in the magazine." For example, the magazine floor of the Mauser rifle is designed to be relatively high, and after the last bullet is gone, the magazine bottom plate will be held up by the magazine spring. In this way, the bottom plate of the magazine will block the bolt, so that the bolt cannot be pushed up in an empty position. After reloading, the bottom plate of the magazine was pressed down, so that the bolt could be pushed up again. Of course, this is not counting the empty position hanging, the bolt was just blocked, and it was not "hanged". Let's call it an empty warehouse block machine for the time being. ”
"When the empty magazine is closed, the small protrusion of the bottom plate of the magazine will push the stopper up, and the movement of the bolt will be blocked by the pushed stopper, thus forming an empty magazine hang-up. When the magazine is loaded, the bottom plate of the magazine is depressed, but the baffle cannot fall due to the friction between the magazine and the bolt. After loading, the shooter pulls the bolt back to separate it from the stopper. In this way, the stopper will fall under the action of its own small spring, so that the hang-up state will be released. Philip said proudly.
Karl realized: "I see! Okay, now it's my turn to perform! Let's start the shooting accuracy test! ”
Ten shooters, including Carl, were in place, and ten brand-new assault rifles were mounted on the gun racks. This shooting accuracy test was to shoot the target in a lying position, and the first thing to do was to shoot at a 50-meter standard target.
In fact, 50-meter shooting is very easy for these veterans, coupled with the high shooting accuracy of the new assault rifle, so after a magazine is fired, everyone finds that the impact point is almost not far from the center of the circle, and it seems that the accuracy of 50-meter shooting is very good.
More than a dozen testers quickly retrieved the target and performed statistical analysis. The results showed that the number of rings of the ten shooters was above 290 rings, and the company's boss Carl had the best result, reaching 300 rings.
The average number of rings in the 50-meter shooting reached 297 rings, which is a very good result. And the R50 and R100 values are also relatively small, with a dispersion area of only about 30 mm, if you express it according to the later MOA-MinuteofAngle, the shooting accuracy of the new assault rifle is only about 2MOA, which is already quite good, and the general sniper rifle is only about 1.5MOA.
It has been calculated that the angle of 2MOA is equivalent to 30 mm at a distance of 50 meters, and a 2MOA accuracy assault rifle will have a random error of 30 mm at a target of 50 meters after it is zeroed. Draw a circle with a radius of 30 mm at the center of the target, and the impact point may be up, left, right, or down when you shoot, and it will not exceed the circle with a radius of 30 mm.
The next 100 meters of shooting, the difficulty is slightly increased compared to 50 meters, but it is not too difficult. Therefore, this shot was not much different from the result of the 50-meter shot, and the highest score was still Karl, who still scored the highest score of 299 rings. However, to his dismay, the highest and lowest grades were eliminated and were not counted in the results.
As a result of the 100-meter test, the average number of rings reached 295 rings, and the bullet dispersion radius R50 was only 35 mm, and the R100 was only 45 mm. Judging from the test results of 50 meters and 100 meters, the shooting accuracy of the new assault rifle at these two distances is much higher than that of mainstream rifles such as the Mauser Type 1898, the Lee Enfield short rifle, and the American M1903 "Springfield" rifle, and the American M1903 "Springfield" rifle has a dispersion radius of 60 to 70 mm at a distance of 100 meters, while the full gun length and barrel length of the new assault rifle are several hundred millimeters shorter than these ordinary rifles! Not to mention the capacity of ammunition, the new rifles can hold 30 rounds in a magazine, while those rifles generally only have 5 to 10 rounds!
The next 400 meters of shooting test can be described as the key, if the shooting accuracy of the new assault rifle at this distance can be much higher than the old rifle, it means that its design and manufacture is very successful, the most important performance parameters of the rifle is the shooting accuracy, shooting power and firepower, firepower needless to say, it must exceed the old rifle by a large margin, the most critical is the shooting accuracy and power.
Philip said seriously: "Everyone, pay attention, this 400-meter shooting accuracy test is very critical, it is related to whether this new assault rifle can pass the shooting accuracy test, so we must eliminate the human factor, everyone must play their best, okay, let's start!" ”
Shooting at 400 meters, in the absence of a scope, is actually more difficult. Philip remembers once reading online that a group of World War II fans had tested a famous rifle from World War II, and the result was a shock. The British's Lao Li became the worst accurate, and there was no guarantee of hitting a human-sized target 300 yards away, which of course was most likely caused by hangfires. The most disappointed was Springfield, which had high hopes in advance. Of the munitions used, there is no guarantee of hitting a human target 300 yards away. Only once did Springfield have a three-fold sight mounted on Leatherwood, which could accurately hit a human target from 500 yards away. The German K98K was relatively better, with a 1,5x ZF41 being able to hit a 300-inch scatter at a distance of 6 yards. But there was a problem at the distance of 400 yards, because of the difficulty of aiming, as a result the dispersion reached 20 inches.
It can be seen that it is still relatively difficult to hit a target 400 meters away. The ten shooters showed their housekeeping skills one after another, and unhurriedly finished firing thirty rounds. When the testers took back the ten targets, everyone gasped, this shot was too accurate, almost all the bullet holes were concentrated near the bull's-eye, and there were not even a few outlier bullet holes.
The final statistics made everyone present even more excited, especially Carl and Philip. In the 400-meter shooting, the highest score was still set by Karl, and the boss shooter scored 292 rings, and the average score of the middle eight shooters was 281 rings. The bullet dispersion radius R50 is only 150 mm, and the R100 is only 170 mm. The result was a surprising result, and the accuracy of the new assault rifle was almost unmatched by any rifle, except for the sniper rifle.
