More About .223 & 5.56 Ammo

.223 and 5.56x45 ammunition are nearly identical but there are a few subtle differences that may help you decide which caliber is best for you. Generally, if you own an AR-15 or other rifle chambered for 5.56x45, you can safely shoot .223 or 5.56 ammunition in your firearm without any trouble. However, if you own a rifle that's designated for .223, you may not want to shoot 5.56x45 ammo. 5.56 cartridges are loaded to slightly higher pressures than most commercial .223 ammunition.

M855 green tipped 5.56 ammo

M855 vs. M193

Both the M855 and M193 cartridges are popular 5.56x45 loads. The M855 is 62 grain and has a steel core, which can help it penetrate armor slightly better than M193. For more details on the differences, check out this article on our blog about M855 vs. M193.

How Much is 223 Ammo?

Generally speaking, .223 and 5.56x45 ammunition is pretty cheap to shoot compared to other rifle options. You'll save money by buying your ammo in bulk and we carry a huge variety of 1,000 round cases for sale here that'll have you shooting all day. If you need a precision round, look to match-grade ammunition. This ammo is loaded with higher quality components and should give you more accuracy than cheaper, bulk range options.

Steel Cased Ammo vs. Brass Cased

Many shooters prefer to shoot steel-cased .223 ammo because it's cheaper than most brass-cased options for sale. Generally, steel cased ammo works well in AR-15 rifles and you shouldn't have any trouble. Some shooters believe steel cased rounds do lead to more wear and tear on your firearms but depending upon your level of knowledge, you may be able to swap out barrels and other rifle components on your own and the money saved on ammo will make it well worth your time.

Steel-cased ammunition manufactured today is not corrosive and it will not harm your .223 or 5.56x45 chambered firearm outside of regular wear-and-tear that you'd get from thousands of rounds of use.

.223/5.56x45 Bullet Types

Range Use

If you're shooting at the range, we recommend you go with a full metal jacket (FMJ) or full metal jacket boat-tail loaded ammunition. These rounds are typically cheap so you can get in as much training as possible within your budget.

Hunting with .223

Yes, you can hunt with .223 ammo in an AR-15 or other rifle. It's very common to hunt hogs and even whitetail deer with .223 ammunition. If you're going to do so, we suggest picking up ammo loaded with soft point bullets or a more sophisticated, polymer-tipped .223 round. These ammunition options are typically a little more expensive but the more sophisticated projectiles will help bring down game humanely.

Precision Shooting

Look for rounds branded as "match" by the manufacturer. We carry some of the best commercial loads available, featuring Federal Match, Winchester Match, Hornady and Barnes.

    Hornady's gel testing at close range from 16" barrel shows dramatic fragmentation and ~ 9" penetration. Shorter barrels or longer distances should equal deeper penetration, and less fragmentation.

    I was surprised on how fast my order got here. It was exactly as shown and advertised. I'll definitely be ordering again

    Good price and fast service! Just doesn't get any better than that!

    This is great ammo for light armor piercing, or varmint disposal, and staying within Geanva convention laws. Since I don't think any governments are buying on here, there are better rounds for whatever you are hunting for. Try HPBT, soft point, OPM, and Power Point depending upon what you are going after!
