What Is 5.56 Ammo?

History

Belgian firearms manufacturer FN Herstal created the 5.56×45 mm NATO, as it is known by its full name. This type of ammo belongs to an intermediate power family of cartridges, known as SS109, SS110, and SS111. It serves as the regulation cartridge for NATO countries, and some non-NATO nations.

The ammo was engineered from a series of other cartridge families, based on the design of the .223 Remington. It was born out of an agreement tendered by NATO in 1960 to utilize a cartridge of lesser caliber to replace their standard issue a 7.62×51 mm. The newer version of  5.56 ammo became standard issue in 1980

Features & Presentation

The 5.56 ammo shell can withstand up to 430.0 piezo service pressure. One of the chief elements of this type of ammo is the fact that when coupled with standard lead core bullets, the penetrator will puncture between 38-51 centimeters, with the tendency to fragment considerably and disperse widely within its target.

Personal Factors

There are multiple brand options available to purchase this type of ammo, but choosing the one that works best for your purposes requires some active forethought. There are several key personal factors which influence the ultimate effectiveness and usefulness of a specific brand of ammo. These include, but are not limited to, personal accuracy, bullet manufacturing, individual stress and capabilities, and environment elements.

Environmental Factors

In purchasing 5.56 ammo that is best suited for use for firearms within the home, you need to examine what your own personal living space consists of. Do you live alone or do you live with other members of your family? Do you have a spouse or significant other in the home? Do any children reside with you, or do you share a wall with your neighbors? The fragmental nature of this type of ammo requires crucial consideration of individuals who share a wall or living space at your place of residence as they could be injured unintentionally during your efforts to protect your home.  

The good news is, the 5.56 ammo of today presents far less risk of hazard to an innocent passerby than its ancestors. With that being said, it is important to select ammo that swiftly separates into a few large sections or enlarges enough to cease movement before exiting out the other side of your target. Not only are bullets that meet these specifications less likely to injure household members; they cause harm to soft tissue leading to quicker impairment of the target.

Using more brittle bullets that are tailored to separate into small fragments also reduces the risk of harm to household members, but tends to limit target effectiveness as well. They are specifically useful, however, in circumstances where the likelihood of ricochet is high.

Bullets known as “Blind-To-Barrier” are engineered to penetrate materials such as sheetrock, a thin sheet metal, thick clothing, plywood, and windshields without compromising their ability to perforate soft tissue and the intended target. They are not ideal for use in situations where household members or neighbors may be caused harm.

Likewise, full metal jacket projectiles are not household friendly. It is important to note that these should only be selected if there is no risk of hitting anyone other than your proposed target.

Something else to consider when choosing the best brand for your 5.56 ammo is that momentum and stability are essential to ensure that fragmentary projectiles accomplish their intended purpose. Bullets need to be matched to the barrel specifications to ensure that they go where they are supposed to and do not diverge elsewhere.

There are a variety of acceptable impetuses to achieve the optimal scope of your firing range and target. In preparing to select the right brand for your, try bullets of varying mass and design to see how your firearm propels and disperses them against your paper or cardboard mark. If the shots do not result in round or predominantly round holes, you will need to experiment with various bullet masses until you achieve balance within your target distance.

Another resource for determining the correct weight and speed of the 5.56 ammo you will purchase is to see if the manufacturer has data published on their product’s performance. Be sure to note the muzzle, impact speed, and barrel lengths from which the data was gathered.

Another important factor to consider is the impact on the ears produced by the projection of no-holds-barred ammo. The discharge sound can be incredibly jarring and distracting when facing a tenuous situation. Sound suppressing equipment is helpful to deal with the barrel’s sound and flash and should be considered when anticipating self-defense measures indoors.

Ammo Types

Bullets largely fall into two categories known as full metal jackets and hollow point/soft points. Full metal jacket bullets are ideal for target practice while hollow point/soft point bullets are better for home-defense and long distance discharges.

In looking at 5.56 ammo, you should be aware that these are military grade bullet rounds. They fall into two categories; M193 and M855. The former is the full metal jacket standard issue in the military while the latter has a “green tip” missile round containing a light gray steel rod.

Bear in mind, the price comparison between the M193 and M855 are close. The latter is better at target penetration but is not allowed inside all target ranges. The M193 is ideal for soft targets within a distance of 100 yards
