Although the 223 ammo and the 5.56 ammunition share many similarities, the calibers of these two types of ammunition are fundamentally different. It is not unsafe to fire 223 ammunition through a rifle that is chambered for 5.56, although doing so is not usually the best option.
However, you should under NO circumstances use 5.56 cartridges in a.223 firearm, since the additional pressure can lead to a malfunction in the firing mechanism. If you keep this safety recommendation in mind, the.223 Remington and the 5.56x45mm NATO cartridges are fantastic options for practicing on the range, protecting your home, and going hunting. We have a large variety of 223/556 rifle ammunition from some of the most well-known manufacturers, including as Winchester, Hornady, and Federal Premium. picture
You may restock your supply of high-quality ammo as well as all of the other hunting, outdoor, and tactical gear you require by shopping with us online at OpticsPlanet. We even have bulk . Ammunition in calibers 223 and 5.56 available for purchase to offer high-volume shooters an even better deal.
Do you have a 223 Rem or 5.56×45 rifle? If yes, order this ammunition. If no, go out and buy a rifle and then order this ammunition. PMC provides the dependable range loads you need to become a better shooter!
This cartridge sports a 55 grain full metal jacket boat tail. As an FMJ, the bullet does not offer the best solution for home defense – you would be much better off with a bullet that can expand, inflict greater damage to surrounding soft tissues, and hopefully stay anchored in the threat where it can’t threaten an innocent bystander.
The FMJ’s jacket is hard enough to ensure reliable passage from the magazine to the chamber, and it is also steel-free and nonmagnetic. The FMJ’s boat tail simply helps to reduce drag, which in turn flattens its overall trajectory and provides some protection against wind deflection.
PMC is in charge of keeping the Republic of Korea Armed Forces stocked with ammo, but they make plenty of 223 Rem specifically for the international consumer market. They’re known for their high-quality components, which include freshly drawn Boxer-primed brass cases. This reloadable ammo is also noncorrosive.
223 ammo academy Ammunition is basically the civilian version of the military’s 5.56×45 cartridge. An excellent round for plinking, self-defense, or varmint hunting, AR-15 shooters love 223 ammo because it’s largely available and provides very little recoil.
The development of the cartridge, which eventually became the .223 Remington, was linked to the development of a new lightweight combat rifle. The cartridge and rifle were developed by Fairchild Industries, Remington Arms, and several engineers working toward a goal developed by U.S. Continental Army Command (CONARC). Development began in 1957. A project to create a small-caliber, high-velocity (SCHV) firearm was created. Eugene Stoner of ArmaLite was also invited to scale down the AR-10 (7.62×51mm NATO) design. Winchester was also invited to participate.
CONARC ordered rifles to test. Stoner and Sierra Bullet’s Frank Snow began work on the 223 ammo wiki cartridge. Using a ballistic calculator, they determined that a 55-grain bullet would have to be fired at 3,300 ft/s to achieve the 500-yard performance necessary.
Robert Hutton (technical editor of Guns and Ammo magazine) started the development of a powder load to reach the 3,300 ft/s goal. He used DuPont IMR4198, IMR3031, and an Olin powder to work up loads. Testing was done with a Remington 722 rifle with a 22″ Apex barrel. During a public demonstration, the round successfully penetrated the US steel helmet as required, but testing also showed chamber pressures to be too high.
Stoner contacted both Winchester and Remington about increasing the case capacity. Remington created a larger cartridge called the .222 Special. This cartridge is loaded with DuPont IMR4475 powder.

223 bulk ammo .223 Remington vs. 5.56×45mm NATO
In 1980, the .223 Remington was transformed into a new cartridge and designated 5.56×45mm NATO (SS109 or M855).
The external dimensional specifications of 223 ammo bass pro and 5.56×45mm NATO brass cases are nearly identical. The cases tend to have similar case capacity when measured (case capacities have been observed to vary by as much as 2.6 grains (0.17 ml)), although the shoulder profile and neck length are not the same and 5.56×45mm NATO cartridge cases tend be slightly thicker to accommodate higher chamber pressures.
When hand-loaded, care is taken to look for pressure signs as 5.56×45mm NATO cases may produce higher pressures with the same type of powder and bullet as compared to .223 ammo price history cases. Sierra provides separate loading sections for .223 Remington and 5.56×45mm NATO and also recommends different loads for bolt-action rifles as compared to semiautomatic rifles.
The Sturm, Ruger & Co. AR-556 has rifling at 1:8. Their Mini-14 rifles have rates of 1:9. Ruger’s American bolt-action rifle is also in 1:8. Smith and Wesson in their M&P15 also uses 1:9.
Pressures on 223 ammo in stock
Remington submitted the specifications for the .223 Remington cartridge in 1964 to SAAMI. The original pressure for the .223 Remington was 52,000 psi with DuPont IMR Powder. The current pressure of 55,000 psi (379 MPa) resulted from the change from IMR to Olin Ball powder. The official name for .223 Remington in the US Army is cartridge 5.56 x 45mm ball, M193. If a 5.56×45mm NATO cartridge is loaded into a chamber intended to use .223 Remington, the bullet will be in contact with the rifling and the forcing cone is very tight.
This generates a much higher pressure than .223 Remington chambers are designed for. NATO chose a 178-mm (1-in-7) rifling twist rate for the 5.56×45mm NATO chambering. The SS109/M855 5.56×45mm NATO ball cartridge requires a 228 mm (1-in-9) twist rate, while adequately stabilizing the longer NATO L110/M856 5.56×45mm NATO tracer projectile requires an even faster 178 mm (1-in-7) twist rate.
