Difference Between .223 Ammo and 5.56 NATO Ammo

One important thing to note about the .223 Rem cartridge is the difference between it and the 5.56 NATO cartridge. The two rounds often get lumped together because NATO modified the .223 in order to make the 5.56 back in 1980. Consequently,the external dimensions of their cases look exactly the same.

One difference between .223 ammo and 5.56 ammo involves the interior of their cases. The walls for the 5.56’s case are thicker than those of the .223, which increases its maximum chamber pressure by 10-15%. This means that the loading data will need to change if someone wants to reload 5.56 cases to .223 specs.

A bigger—and more important—difference between the .223 and the 5.56 lies in the rifles that fire them. A .223 round will fit in the chamber of a rifle designed for 5.56 cartridges and vice versa. However, issues can arise when someone tries to fire 5.56 rounds in a rifle that designed for .223 ammo.

Because the leade of a .223 rifle is almost half that of a 5.56 barrel, 5.56 rounds can end up touching the rifling of a .223 barrel. This can increase the pressure inside the chamber and lead to cases stuck in the chamber and blown cases. It can also lead to misfires, which can possibly cause damage to the rifle.

The bottom line is this: If you have a rifle chambered in .223 ammo—especially a bolt action rifle—use .223 ammo. Almost all MSR’s and AR-15’s are chambered for 5.56 ammo. If you are not sure which caliber a firearm is chambered for, it will be stamped on its barrel or lower receiver.

Finding the Right .223 Ammo Weight

The weight of .223 Rem cartridges is 30-90 grains. This broad range is what makes this round so versatile. Shooters who want to focus on target practice can do well with 55-62 grain rounds. If you want something for hunting or competitive shooting, look for rounds with a higher grain.

The Best Kind of Firearm for Apartment Defense

Image
There’s a wealth of information and opinions available regarding the best weapon for home defense. However, there’s a surprising lack of relevant info specifically regarding the sort of defense weapons that work best for defending an apartment. It’s an odd oversight considering that there are more people renting right now than there have been since 1965. Basically, the issues that apply to any home defense situation apply to apartment defense—except that there are more shared walls and more people behind them in an apartment complex. The population dynamics of apartments make choosing a weapon with a lower likelihood of over-penetration far more important. The last thing anyone wants to do is inadvertently endanger the safety of a neighbor should the worst-case scenario require firing a gun to protect yourself in an apartment building. Of course, there are way too many specific calibers, loads, and variations (not to mention the thousands of brands and models) to pr...

Some Info on .223 Ammo

Image
There is no denying that . 223 ammo —also known as the .223 Remington—has plenty of qualities to recommend it. Read below for some info on this popular rifle cartridge—how it came about, how it performs and what people can use it for. A Brief History of the .223 Remington The roots of the .223 Remington rifle cartridge go back to the 1950s, when the US Continental Army Command (also known as CONARC) wanted to create a SCHV (small caliber high velocity) firearm. CONARC approached ArmaLite gun designer Eugene Stoner and Winchester to create a rifle that met these parameters: • Used .22 caliber bullets • Bullets could exceed supersonic speed at 500 yards • Weighed 6 lbs. and had 20-round magazine • Could switch between semi-automatic and full auto • Bullets could penetrate .135” steel plate or one side of a US steel helmet at 500 yards • Could match ballistics and accuracy of M2 ball ammunition • Could match wounding ability of M1 Carbine Stoner...

A Closer Look at the Ultra-Versatile .300 AAC Blackout and Why the Buzz Is True

Image
The . 300 AAC Blackout has increasingly become established as the alternative caliber for the AR-15. With the exception of the forever-popular .22LR, it's very likely that more people are shooting .300 AAC Blackout from AR-15s than anything but the .223 Remington. It's not like there aren't other excellent calibers for the AR-15 platform that remain popular. But whether Grendel or SOCOM, Creedmoor or Valkyrie, propelled by buzz or hype, Blackout has rocketed past them all in popularity. While there are inevitably going to be shooters for whom it’s just not their cup of tea, that popularity isn’t just hype or an overrated, flavor-of-the-month cartridge. The .300 AAC Blackout has earned its place in the top echelon of centerfires with impressive versatility. Small and Medium Game While the .300 AAC Blackout was originally designed as an AR-15 (M4) compatible suppressible military cartridge to provide a harder thump for close-quarters combat, the civ...
