There are many types of metal rifle cartridges. The.270 Winchester is included in the.30-06 family. The.280 Remington is part of the.306 Winchester family. The.243 Winchester cartridge and the 7mm-08 Remington cartridge are part of the.308 Winchester family. The.223 Remington has its own family but it was based upon the.222 Remington (1950), which is a proprietary cartridge. This will allow you to convert with only a barrel or barreled receiver. The cartridges are all from the same family so you don’t have to replace the bolt carrier. Here’s a look inside the.223 Remington and the family AR-15-compatible cartridges that it has produced. Wilson Combat now offers a 30-round magazine compatible with the.223 Remington and the.300 Blackout.
The M16, the full-auto version civilian rifle now known by the AR-15 or, in politically correct circles, the MSR (modern sporting gun), is directly linked to the development of the Remington.223 Remington. Although the military would eventually replace the.223 Remington by the 5.56 NATO, it didn’t affect the popularity of the cartridge. It has been very popular for competition, hunting, and self-defense since its introduction. It has produced many excellent offspring but it remains the most popular chambering. Although it is not legal for big-game hunting or deer hunting, it is legal in more states than it is for. Factory ammunition is limited to the.308 Winchester. The most important thing is that the.223 Remington was the basis of five other cartridges that are now viable options for the AR-15. 5.56 NATO (1980).
The best way to describe 5.56 NATO, which was designed to provide better reliability and performance in the M16 military application, is to say that it’s the identical twin with better performance. It was the twin that became the family’s career soldier. Externally, the.223 Remington is identical to the 5.56. The real differences involve maximum average pressure (MAP) and how the chamber is cut into the barrel.The 5.56 NATO is a dimensional twin to the .223 Remington, but the cartridges aren’t 100-percent interchangeable.Regarding pressure, 5.56 NATO ammunition is loaded to a MAP of about 58,000 psi. The.223 Remington can be loaded at a MAP of 55,000psi. The throat of the chamber for 5.56 NATO is also 0.125 inches longer. These differences mean that if you fire a 5.56 NATO round in a rifle chambered to the.223 Remington, pressures could reach up to 65,000 psi. This is dangerous and can cause primers or even a firearm to fail. It’s safe to use.223 Remington ammunition in a rifle that is chambered for 5.56 NATO. Although accuracy and reliability are not optimal, it is safe. The Ruger (2004)
Many families have one member of the family who never seems to grow up. They are smart, cute, and great at their jobs, but they never seem to be very popular. The.204 Ruger is an example of this. Although the.222 Remington Magnum has been credited with being the parent case of the.204 Ruger’s.204 Ruger,.222 Remington Magnum looks more like its older brother, the.223 Remington. The.222 Remington Magnum, however, has fallen into obscurity. Although it was not intended to be used in the AR-15, its.223 Remington-sized 0.378 rim and 2.26-inch overall length make it a good choice for MSRs. It’s popular for shooting prairie dogs and bobcats, as well as coyotes and foxes, because of its speed and explosive results against small vermin. Although ammunition is readily available from most major manufacturers, there are only about 20 factory loads. Bullet choices are limited.
The.300 Blackout is the coolest kid in the.223 Remington clan. Advanced Armament Corporation (AAC), developed the cartridge to provide intermediate ballistics similar to the 7.62×39 Russian cartridge. It also performs very well as a subsonic bullet. Although Remington and AAC are the ones who claim credit for the development of this cartridge, it was actually developed by J.D. Jones as a wildcat. The.300 Blackout was formerly known as the Jones.300 Whisper. It’s the AR-15’s best subsonic cartridge. On the other hand, it’s small enough to be used for smallish, big-game hunting or limited tactical applications. Jones shortened the.223 Remington gun and made it smaller to accommodate a.30-caliber bullet. AAC and Remington reworked Jones’ idea and submitted it to SAAMI. The rest is history. The.300 Blackout, next to the 5.56 NATO/5.223 Remington, is the most popular AR-15 chambering. Smart marketing and a cool name are two of the reasons for the Blackout’s success. The availability of supersonic and factory subsonic ammunition is another reason for the Blackout’s success. Subsonic ammunition and a suppressor can be used to silence shooters, while supersonic loads can be used to tackle feral hogs and deer. Although subsonic blackout loads were not able to deliver a good terminal performance in the early days, there are many expanding subsonic options today. It is rare that an AR-15 can shoot subsonic and supersonic loads accurately. Sometimes, a.300 Blackout cartridge has been chambered in a Remington.223 Remington. There have been instances where a.300 Blackout cartridge was chambered in a.223 Remington.
Some kids are gifted at all he attempts. He excels at soccer, basketball, and track. He is smart, attractive, and seems to be able to get the girls. The.300 Hamr is the most distinguished Remington cartridge. Designed by Bill Wilson of Wilson Combat and shortened to.223 Remington, the.300 HamR is necked to.30 caliber. The cartridge was approved by SAAMI in 2020. It will work with bullets between 95 and 150 grains. It has similar or better external and terminal ballistics to the.30-30 Winchester, and is suitable for big-game hunting. The.300 HamR is similar to an athlete who excels in one sport but is often remembered for only one. Wilson Combat initially referred to the.300 HAMR as the best big-game cartridge for AR-15. This is the most common use of the cartridge. The.300 HAMR is also able to perform admirably in a tactical environment due to its wide range of projectiles (Wilson Combat currently has 14 loads), and the fact that it can be used with everything from mono-metal to bonded bullets. Wilson Combat now offers a multi-caliber 30-round magazine with a 30-round capacity that will work with the.300 Blackout,.223 Remington, and the.300 HAMR.
The.350 Legend is a bit like the fat uncle who drives a Chevy Nova and smokes cigars. He also tells great jokes and consumes all the beer in the fridge whenever he visits. It’s a little oddity when you think about cartridges. Most cartridges are designed to deliver a level or terminal ballistics that is not possible with the parent cartridge or any other cartridge within the family. Although the.350 Legend does this, Winchester created it with the.223 Remington case as a base. The.350 Legend case has a minimal taper to a bullet diameter 0.357. The.35-caliber bullets and the absence of a shoulder allowed it to comply with straight-wall deer hunting cartridge regulations and feed and function in an AR-15. This cartridge has been surprisingly popular from coast to coast. It has a good big-game hunting performance beyond 200 yards and minimal recoil. It is a great deer hunting rifle in an AR-15, or a compact bolt action rifle for young, recoil-sensitive shooters.
The.22 Nosler 2017 is a crossbreed cartridge. As with many human families, there can be a little bit of cheating that can lead to a bastard. The.22 Nosler case is not based on the Remington.223 Remington. It’s instead based on a 6.8 SPC case (2002 cartridge case), which is actually a descendant from the.30 Remington (1906). However, the.22 Nosler can be converted to any AR-15 chambered to fit any cartridge in the family of.223 Remington cartridges to the.22 Nosler. They reduced the rim diameter from 0.422 to 0.378 inches in the 6.8 SPC case. The.22 Nosler cartridge cartridge case is slightly bent because its rim is smaller than the cartridge’s base diameter. The.22 Nosler is comparable to the.204 Ruger in terms of velocity and outclasses both the.223 Remington. Limited availability of factory ammunition is the downside.
