What is the difference between brass and steel casing?

Brass ammo is generally considered to be better than steel-cased ammo because it creates a better chamber seal than steel. Thus you have less blowback into the chamber and the receiver. Brass is better at this sealing action because it is more malleable than steel. So, it expands to snugly fit the walls of the chamber.

Why is steel case ammo bad for your gun?

While I don’t generally recommend steel cased ammo, it’s not going to hurt your rifle in limited amounts. The other problem with steel cased ammo is that the cases don’t expand the same way that brass cases do. This causes carbon build up between the case and the chamber wall. This build up can cause stuck cases.

Does steel case wear more than brass?

So, yes, steel-cased ammo will wear your AR-15 out faster than brass ammo will. Both bores and barrels of the rifles that fired steel-cased/bimetal jacketed ammunition were basically unserviceable.

What is the downside to steel cased ammo?

Perhaps the biggest drawback to steel-cased ammo is that it is not easily reloadable. For some shooters, this is not a big hurdle as the ammunition is so cheap that reloading is not a major issue. It would probably cost more to process and reload 1000 rounds of steel cased ammunition than to buy a fresh case of ammo.

Is Wolf ammo steel cored?

Wolf Ammunition contains lead projectiles with bimetal jackets and are not steel core. They make projectiles in Full Metal Jacket (FMJ), Hollow Point (HP), Soft Point (SP), and Full Metal Jacket Boat Tail (FMJBT).

What is steel case or steel core ammo?

Steel case normally means the case is steel in stead of brass, not the bullet. What brand did you buy? And FMJ just means the core is encased in a “one piece” metal jacket. It has no designation for the metal material.

Can I shoot steel case ammo in my ar15?

Now, on to some myth-busting. Modern production steel-cased ammo is not corrosive, even when Berdan primed and it will not destroy your extractor. The ferrous bi-metal jackets found on most steel-cased ammo will not damage the rifling of your AR and are perfectly safe to use on any rifle-rated backstop.

What are the disadvantages of steel cased ammo?

The many cons:

• steel rusts, so cases have to be lacquered to control corrosion. This lacquer burns off and can potentially foul the chamber.
• Steel cases are more difficult (if not impossible) to reload. Steel is harder and less malleable than brass so it’s a lot harder to accurately resize the cases after firing.
