There is a lot of debate among gun enthusiasts about whether steel-cased ammo is bad for AR15s.

Some people say that it causes more wear and tear on the gun, while others claim that it’s just as good as brass-cased ammo.

So, what’s the verdict?

Is steel cased ammo bad for AR15?

Here’s a look at the pros and cons of steel-cased ammo.


  • Steel casing is cheaper than brass, so you can save money by using it.
  • It’s not as susceptible to damage as brass, so it may be a better choice for high-volume shooting.
  • Steel fires slightly hotter than brass, which can help improve accuracy in some firearms.


  • Steel is harder than brass, so it can cause more wear and tear on your gun (especially the chamber).
  • It’s not as easy to reload steel cases, so you may have to buy new ammo more often.
  • The increased heat from firing steel ammo can potentially shorten the life of your gun.

So, there you have it. The pros and cons of steel cased ammo. Ultimately, the decision of whether or not to use it is up to you.

AR15s are pretty versatile when it comes to the types of ammunition they can fire, but there are some general things to keep in mind when using steel-cased ammo.

Is steel cased ammo bad for AR15?

First, because steel is harder than brass, it’s more likely to cause wear on the chamber and rapid-fire components like the bolt carrier group. That’s not necessarily a bad thing – thousands of rounds fired with steel-cased ammo will eventually lead to wear and tear regardless – but it is something to be aware of.

Second, steel-cased ammo is generally less accurate than brass-cased ammo due to the way the cases are manufactured. That said, if you’re just plinking at targets or doing some casual range shooting, steel-cased ammo is perfectly fine to use.

In general, the best advice is to use the same ammunition that your local law enforcement officers use. They’re the self-defense experts, and they’ve researched to figure out what works best in a given situation. Of course, every situation is different, so it’s always a good idea to consult with a qualified firearms instructor before making any decisions about self-defense ammunition.

There are a few things to consider when making your decision.

Pros of steel cased ammo:

  • It’s generally cheaper than brass-cased ammo.
  • It’s often available in larger quantities than brass-cased ammo.
  • It can be reloaded just like brass cased ammo.

Cons of steel cased ammo:

  • Some people say it wears down the internals of an AR15 more quickly than brass-cased ammo.
  • It can be tougher to extract if a round is fired without lubrication.
  • Some types of metallurgic steels used in ammo cases can be harder on extractor claws than brass.

So, what’s the verdict? Ultimately, it’s up to you. If you’re looking to save a few bucks or buy in bulk, steel-cased ammo is a great option. Just be aware of the potential drawbacks and make sure to clean your rifle regularly.

No, steel-cased ammo is not bad for AR15. It can be a great option for those looking for an affordable and reliable round. Steel cased ammo is often loaded with a full metal jacket bullet, which means it will penetrate targets well and is ideal for range training. Plus, steel-cased ammo is less likely to expand on impact, so it can be a good choice for home defense situations. Just make sure you clean your gun regularly when using steel-cased ammunition to prevent buildup that could lead to jams or other problems.
