Left: brass pellet after the first draw; center: two intermediate-stage draws of copper-washed steel Cuban cases found in the ballast bag of a Cuban freighter in an Italian harbor; right: finished 7. Patriotic War and then recommenced and finalized in Others have stated that it was derived from the German 7. This latter scenario is highly unlikely, as the Soviets would have required specimens of 7.
Whatever the case, the Soviet M43 cartridge is a true intermediate assault-rifle round. The first prototypes featured cases that were The case was trimmed to Color codes on a projectile's tip are used to identify the type of ammunition. Left to right, caliber 7. Special-purpose loads have included heavy subsonic ball for use with sound suppressors , practice blanks, short-range loads and drill rounds.
Ball ammunition will be encountered in two configurations. Most prevalent is a grain boattail bullet, which usually consists of a copper-washed steel jacket, lead and antimony sleeve and a mild steel core Soviet Type PS.
Yugoslavia's M67 ball ammunition, as well as that of several other countries, uses a flat-based bullet of approximately the same weight with a copper-alloy jacket and lead core.
Muzzle velocity of both types is between 2, and 2, fps. In its boattail configuration, the 7. At that distance the bullet will yaw to less than 90 degrees, then come back down to a point-forward position and finally yaw degrees — ending its travel in a base-forward position.
Bi-lobbed yaw cycles of this type are commonly observed with pointed, nondeforming bullets. Total penetration in living tissue is almost 29 inches. Abdominal shots usually exhibit no greater tissue disruption than that produced by a. However, of course, this round is capable of inflicting such damage at far greater ranges than a handgun would. When I was working at the Wound Ballistics Laboratory at the Letterman Army Institute of Research in San Francisco, we tested the lead-cored, flat-base Yugoslav bullet and found it to be considerably more effective.
It commences its yaw cycle after only three to four inches of penetration. Once again, the yaw cycle is generally bi-lobed. The bullet reaches its maximum penetration of 23 to 26 inches traveling base-forward, somewhat flattened and retaining almost all of its original weight two or three small fragments are shed in the area of maximum cavitation. Although the flat-based 7. If we have neither mushrooming nor fragmentation, yawing is all that remains to maximize tissue disruption and enhance the bullet's performance — provided that we do not sacrifice penetration.
The 7. Development of the 5. Research on the concept began in the late s. Engineer Viktor Sabelnikov headed the project. The rimless 5. The grain boattail bullet has a gilding-metal-clad steel jacket. The unhardened flat-tip steel core is covered by a lead sleeve that does not fill the entire interior of the jacket, leaving a hollow cavity inside the nose — the focal point of the imbroglio over wounding potential.
Although adopted by the Soviet army in , the 5. Here are a few Kalashnikovs chambered for the newer round, top to bottom: Polish Tantal AK74 known in Poland as the wzor , Russian AK selective-fire version three-shot-burst mode and Bulgarian "Krinkov" a complete misnomer with 8. Large-caliber steel cores, such as the hardened penetrator of the U.
It would be difficult to screw-turn, or even swage, a pointed tip on the 5. I personally believe it was simply more cost-effective to fabricate a flat-tipped core and leave an air pocket under the jacket's tip as long as it did not affect the projectile's aerodynamic qualities.
After some time in the field, reports came back that this rifle was prone to jamming caused by mud, dirt, and other debris which compromised the moving parts. This created many malfunctions, especially the "failure to extract" malfunction.
Classic AR rifle. Even though the AR started out with some major issues, the modern-day version has addressed and resolved the issues this type of rifle had during its early days. As a result, this rifle is still in service today. This rifle is extremely accurate and, when placed in the hands of a skilled shooter, can be pushed to its very limits by shooting accurately past its effective range and stopping a threat.
It is very ergonomic due to its design and the minimal recoil. This makes it very easy to control even when you fire it rapidly. Now that I have talked about both the pros and cons of both rifles, I am going to give you my opinion on them and which one I prefer. To put it plain and simple, I am an AR man. I'm not saying I don't love the AK rifle and appreciate everything about it, I just prefer the AR, the reason being that I have trained on that platform and fell in love with it right from the beginning.
The accuracy of the AR is awesome and, combined with its ergonomics, makes it feel very natural to manipulate during various training exercises. Also, I am a firm believer that the AR is a very reliable rifle. All the ARs I have owned or built have withstood abuse from training and have never let me down. I can confidently engage targets from a long distance with accuracy. If given the opportunity to train frequently with a quality AK, I feel as though I would be able to appreciate it as much as I do my ARs.
But for now, in my opinion, the AR is the winner in this debate. The rifle can function with minimal cleaning and maintenance. It is very easy to field strip and operate.
The AK shoots a 7. With this larger caliber, the AK has greater "stopping power" than the 5. AKs are generally inexpensive, even though there are some modern day high end AKs on the market, the rifle is usually cheap pricewise. The round that the AK fires 7. Cons: The effective range for the AK is between yards, which is a couple hundred yards less than the effective range of an AR There is no deficit of options for brass cased 7.
You can find it from both American and European manufacturers, ranging from range cartridges with simple FMJ projectiles to rounds with more advanced bullets that better suit the AK for self-defense and hunting. Whichever type of 7. It would be an understatement to describe it as merely satisfying. JavaScript seem to be disabled in your browser.
