We will compare these ammunition types based on our knowledge to help you understand the difference between the two. In addition, we will also outline the pros and cons of each.

So let’s read to the end of our post to avoid missing valuable information.

Overview of 223 

Like the 6.5 Creedmoor, the .223 cartridge is also a new member of rifle ammunition. Remington created it in 2007, and it quickly became popular with shooters within the first year of its release.

This short-action cartridge can push one 55-grain bullet at more than 3,000 feet per second. It is high-speed ammunition and is one of the few options that can rival the 6.5 Grendel regarding velocity.

It is made to be able to quickly and easily take down games, such as prairie dogs or many small animals.

It allows you to shoot targets as far as 500 yards accurately and still works well at closer distances, such as 300 yards. But this cartridge generally is not as versatile as others like the 6.5 Creedmoor or 6mm Creedmoor.

Many gun experts or skilled shooters argue that the 223 cartridge is slightly more potent than its .22LR counterpart. Many shooters and hunters do not consider the 223 ammunition feasible for their sport.


  • Cheap to produce
  • Reload quickly
  • Lightweight rounds


  • Lower velocity
  • Lower ballistic coefficient

The 6.5 Creedmoor is relatively new ammunition. Hornady developed it, and it was SAAMI certified a short time later. These bullets have cases that are more efficient than that of the .308 Winchester.

This ammunition is ideal for many hunting medium-sized games, such as hogs, deer, and large animals like mountain lions and bears.

Initially, this ammunition is well-suited for long-range shooting. It has even had remarkable records in competitions ranging from Palma to F-Class.

You can use this versatile cartridge on everything, such as elk or prairie dogs. It even works well with targets about 1,200 yards away.

Although the 6.5 Creedmoor is incredible long-range ammunition, it also does the job well at a short range for varmints.


  • Low recoil.
  • Fit in the AR-10.
  • Simple to reload.
  • Low chamber pressure.
  • Good buck wind and gravity.


  • Ideal for the shorter-range shooter.
  • Poor accuracy at long range.

In our experience, the .223 is less accurate than the Creedmoor 6.5 ammo, though the difference isn’t huge.

Both cartridges will generally provide shooters with excellent efficiency and accuracy with their reloads. You can expect to make accurate shots at long distances regardless of your choice.

If these two cartridges go head-to-head in an accuracy contest, we think the results would be pretty even.


If you’re looking for something more effective at a longer distance, the 6.5mm CM beats the .223 Winchester.


If the recoil is one of the elements that interest you most, the 6.5 Creedmoor is the way to go. The .223 Winchester is the high-speed ammunition that may produce a few severe kicks.

Although the 6.5 CM ammo features the same velocity, it delivers more energy that reduces recoil.


Veteran gunners know that the 223 is “all-purpose” ammunition.

Although it is not ideal for long-range, the more negligible recoil and lighter weight make it work well in handling targets quickly within 300 yards.

In addition, the 223 ammunition has relatively low recoil, making it a perfect choice for beginners, chronic pain sufferers, or any other illness that limits their ability to control recoil.


When it comes to hunting, these two options seem to be on par, and it can be challenging to decide which is better.

Options work well for games up to 400 yards or even further. Yet, we believe the 6.5mm Creedmoor is better at longer ranges because it has more energy.


A box of 20 6.5 Creedmoor costs around $6.00, while a .223 box of 20 is about $5.00. But as we can see, the difference is negligible.

If a bullet is loaded in your gun, but you haven’t shot, it will not cause any hazards. Yet, if you just shot a bullet previously, chances are high that it will have unburned powder left, so you’ll need to be careful.

You must also consider the recoil you need or are ready to deal with.

The smaller cartridge features less felt recoil than the larger caliber as it typically uses a lighter weight projectile that leaves a gun’s barrel at a higher speed.
