When you go to buy ammo, you will probably come into some that are labeled NATO rounds while other ammo is just regular ammo. NATO grade bullets are military grade and not meant for recreational use such a hunting game or shooting sports. Their standards are for military combat situations. The standardization helps troops in the field to share ammo with allies that use the same standardized ammo. This new round became widely known due to its effectiveness and ease of use.
After the 5. This is how the came into being. As such, the is a civilian version of the military grade 5. A common question with gun users is the compatibility of two cartridges with firearm magazines. The simple answer is yes, you can load rounds in a 5. Just be sure to note that the ammo loaded in the 5. The opposite is even more important.
If you load 5. This is due to the higher pressure created when a 5. Due to the potential danger that comes with firing a 5. This chamber enables the safe firing of the 5. It does this by having an identical chamber angle with that of the 5. The free bore also gives a tight fit to the bullets, thus enhancing the accuracy and handling of bullets fired from it.
When fired, the 5. However, due to natural conditions that include gravitational pull, the atmosphere, wind, and the angle the bullet is fired from, the 5. The effective range for 5. In this range, the bullet will have maximum effect on the target. Beyond this, expect less impact on the target you are aiming at. The long range makes this a good projectile for the battle field because soldiers can aim and drop targets who are far away with effectiveness.
Similar to the 5. The bullet starts losing altitude and velocity with time reducing the impact that the bullet has when it finally reaches the target.
Due to the longer throat that the NATO chamber employs this combination will cause a chambered weapon to run at approximately 65, psi or more. This is NOT safe and will cause primers to back out, or worse, cause harm to the operator, the rifle, or both. The reverse of this is firing a Rem cartridge in a 5. Due to the throat difference between the two chambers a Rem cartridge may not work optimally in a 5.
In addition, extensive discussions with gunsmiths, ballisticians, and laboratory technicians were conducted. My findings, and the opinions of many experts in the industry who deal with the topic every day, were not exactly what some might expect. In fact, many of them had already discovered what I am reporting, although my research was conducted independently. This article is not a recitation of previously existing information. However, I attempted to write it in a manner which should be easily understood by all — so if you want to read the whole thing, you will come away with a more complete understanding.
See more information on the 5. The development of what has become. You can find an excellent history of this development on SniperCountry. There is little point in restating what has already been written well. Only the dimensions and pressures of. Because SAAMI specifies that pressures must be measured one way and the military specifies that they must be measured a different way, a direct comparison of pressure results from one lot of 5.
Theoretically, any manufacturer could make ammunition which exceeded the maximum pressure specified by SAAMI for the. As you can see from this short excerpt from a page specification for US Military ammunition, military requirements are very exacting. But those military clients are purchasing ammunition for military rifles, which brings me to the next difference between the two: chamber dimensions.
Summary: While. Partially because of this, ammunition pressures are measured differently between the two, and cannot be easily compared. Still, it is generally agreed upon that 5.
The possible results from this, you may have been told, can be catastrophic — the destruction of your firearm, and, at the same time, you might be injured or killed. In reality, the likelihood of encountering such a chamber outside a testing lab is incredibly small.
At the other end of the spectrum are 5. Sometimes, even 5. In between are chambers designed to balance pressure and accuracy, for the long freebore and throat dimensions of 5. Burning an identical powder charge in a smaller space will result in higher pressures. Making an apples to apples comparison of the authorized pressure of the two rounds is difficult because the.
Correspondingly, 5. The chamber dimensions of rifles chambered for the two cartridges are slightly different as well. Generally speaking, a shorter leade results in increased accuracy at the expense of increased pressure and decreased velocity while a longer leade produces increased velocity with lower pressures at the expense of reduced accuracy. The 5. Military to use in the M rifle. Indeed, the MA1, MA2, and M-4 rifles and carbines commonly used by the US Army and Marine Corps as well as the other branches of the military over the past few decades are all chambered in 5.
However, the MA1 has a slower rifling twist rate than the other two since it was designed to use different bullet weights. Due to the military roots of the cartridge, the 5. Since, all other things being equal, a shorter leade results in higher chamber pressure when compared to a longer leade, this means that firing 5. Indeed, not only is it safe to shoot in a chamber and 5. Can you shoot in a 5. Can you shoot 5.
Do not shoot 5.
