22LR vs 223 (5.56mm), what's the difference? (2023)

Do you want to know the difference between 22LR and 223? Let us begin! Photography is a big part of my life. My father raised me around guns and taught me the basics when he was very young. I can't even remember the first time I shot one.

However, I remember being afraid of guns. I was afraid of going backwards. They were loud. If you were trying to get me to shoot someone I don't recognize, I'd be hesitant at the idea. So the .22LR was my salvation. A short, fun, no-kick round that made me want to shoot more than anything else in the world.

The Colt Huntsman became my best friend when I photographed it in the mountains of western Maryland where my father grew up. We wanted to visit my grandfather and take a full load of hunting rifles and the coveted "mine."Colt Hunter .22🇧🇷 I would shoot this gun for hours, spend almost no money and feel like the king of the shooting world. Later he would learn to love weapons like that.Brown BL22.22 leverage and just about every weapon I could get my hands on.

But unfortunately I was not the king of the shooting world. I was a 10 year old boy living the dream.

While I am by no means a perfect gunslinger or marksman, I have learned to like all weapons better, including the ever-popular .223 (5.56 NATO) ammo and the AR, or modern sporting rifle platform.

(Video) 223 -vs- 5.56: FACTS and MYTHS

But you might be wondering how anyone can compare a .22LR to a 5.56/.223. One is a "high performance" round and the other is for squirrel hunting and plinking. But it's not so easy.

22LR vs 223 (5.56mm), what's the difference? (2)

Why do people say that 5.56 or .223 Remington is basically a 22LR?

Well, that's relatively easy to explain. You can see that they are quite different from a layman looking at a fully assembled .22LR cartridge and a .223 or 5.56 cartridge.

The term gauge is often misused. The gauge is actually the diameter of the slot in the hole. Calibers are expressed in 1/100th of an inch, which determines the diameter of the projectile.

22LR vs 223 (5.56mm), what's the difference? (3)

When they say that .223 and .22LR are the same, the cartridges have the same bullet diameter. Although the shell of the bullets is not the same and the bullets may look completely different, they are the same diameter at .223″.

So why is 0.223 called 5.56mm?

5.56mm is just the metric equivalent of 0.223″. Because the metric system is a much more popular unit of measurement around the world, NATO (North Atlantic Treaty Organization) uses 5.56 instead of 0.223 Remington.

But 0.223 and 5.56 are different, my friend says!

Well, your friend is right. BUT, and this is a big BUT, they are dimensionally identical except for minor areas. If I gave you one of each round, you probably wouldn't know the difference.

The biggest difference between .223 ammo and 5.56 NATO ammo is how hot the load is, or do you know it has more powder in it.

The biggest thing to worry about when doing this is the chamber pressures. With the introduction of the .223 Wylde, the standard .223 barrel/chamber was a thing of the past. 5.56mm NATO ammunition typically has a higher PSI chamber pressure and5.56mm should not be fired through a .223 rifle🇧🇷 But oneThe .223 cartridge shoots perfectly in a 5.56mm rifle.

The biggest conclusion is that the amount of dust is the biggest difference in the0,223 vs 5,56 mm redondo.

Why not just shoot a .22LR instead of a .223 Rem or 5.56mm?

That's an interesting question and somewhat valid after someone told you they shoot the same size.

Finally, the .22LR is cheaper, sometimes easier to find, has less recoil, is the most widely used ammunition in the world, and the guns are usually light, just like the ammo.

But although the bullets have the same diameter, they do not have the same grain.

WAIT A DANG MINUTE, WHAT DO YOU MEAN, GRAIN? THEY SAID THEY ARE THE SAME SIZE.

I know that I know.We have one more part of a sphere to address. The grain of a bullet is literally related to its weight.

Again, the grain refers only to the weight of the bullet. Does not include case, powder or primer. So we're only talking about the part that flies through the barrel and hits the target.

Bullets come in a variety of grain weights, giving the bullet different trajectories, thermal ballistics, and velocity.

The choice of a grain generally depends on several factors, including but not limited to:

  • What is the goal of the round?
  • Is weight a factor?
  • Is cost a factor?
  • Do you need a lot of energy released on impact?
  • Is this a round just for fun?

After asking yourself some of the questions above, finding which bale of grain to buy will become a much easier task. If all you care about is sending your balls through paper targets for fun, then cost is the biggest factor.

Availability of 22LR and .223

During the COVID-19 pandemic, the availability of firearms has become ridiculous. Ammunition is probably the hardest thing to find in the world of firearms.

If you could find it, the price was so high you'd think it was a sniffing dog!

Only recently have 22LR and 223 ammunition been restocked. You can check out sites likeBrownells,Palmetto State Armory,lucky scorer,accurate shot, zWaffen.comfor the ammo available if you buy something.

Ammo is 22LR vs. 223

One of the main differences between the 22LR and the 223 is the quantities each ammunition is sold in.

22LR is usually sold in 50, 250 and500 round blocks🇧🇷 They are called blocks because the package is usually in the form of a block and contains a large number of 22LR cartridges.

223 is sold in boxes of 20 rounds and is typically sold in increments of500 and 1000 rounds.

center fire vs edge fire

You will see that one of the main differences between the .22 round and the 5.56 round is the rimfire and centerfire.

Each round has a playbook. When the primer is struck, it ignites a spark that ignites the powder, which expands and causes the bullet to fire.

The primer on a 5.56mm centerfire cartridge is located in the center of the case and is usually a circle. Whereas in the .22 cartridge, the primer is contained in the rim of the cartridge and can be struck anywhere on the rim to fire the powder.

Center shots are known to be more reliable and consistent when shot than rim shots, which sometimes fail to fire when hit.

Manufacturing processes are constantly being improved. Although I've had nothing but good experiences with all the .22 LR cartridges lately, it still suffers from the taint of being a less reliable cartridge than the 5.56 medium cartridge.

.22LR ammo is ideal for long range weapons like .22LR ammoKelTec CP33is inRuger SR22pistols. Conversely, you can use the 5.56 cartridge in serious service rifles like theNoveske N4 PDWand other AR-15 pattern rifles.
