5.56 NATO & .223 Remington Differences
The 5.56x45mm and .223 Remington cartridges are similar in many ways, but there are some important differences to be aware of.
The 5.56x45mm cartridge is the standard cartridge for the NATO military, while the .223 Remington cartridge is primarily used in civilian firearms. The main difference between the two cartridges is the pressure levels at which they operate. The 5.56x45mm cartridge is designed to operate at a higher pressure, which allows for longer ranges and more power. It also has thicker walls, which makes it safer to use in rifles with a chamber that can fire both .223 Remington and 5.56x45mm.
The .223 Remington cartridge is designed to operate at a lower pressure, which makes it safer to use in rifles that are chambered specifically for .223 Remington. It also has thinner walls, which makes it more accurate at longer ranges. However, this lower pressure also means that the .223 Remington cartridge will not have the same power and range as the 5.56x45mm cartridge.
It's important to note that while the two cartridges are similar in appearance and may fit in the same rifle, they are not interchangeable and using the wrong cartridge can cause damage to the gun or injury to the shooter. Always check the caliber of your rifle and use the correct ammunition.
