![]() Brass is more forgiving since it is almost self lubricating (often you can machine work brass without using lube) while you do use lube to machine steel. If steel cases aren’t extracting well then maybe your chamber is rough. Ever see a spring made from steel? All the time. Ever see a spring made from brass? Me neither. Steel doesn’t spring back and therefore doesn’t extract properly.īrass does not spring back, like copper it retains its last form. What’s your experience with steel case ammunition? Tell us whether you are in the love it or hate it camp (and why) in the comment section. After all, saving 30 to 50 percent on your ammo over the course of thousands of rounds will certainly outweigh the cost of a new barrel, perhaps even the gun in some cases. Steel certainly has its place and as I said, over time the cost savings of the ammunition will equal or outweigh the extra wear and tear. That way you won’t get stuck with a bunch of ammo that you can’t use if it doesn’t work in your particular gun. I suggest trying a box or two before buying a large quantity. Steel case ammo is cheaper to shoot and generally works well in most firearms, but does have some downsides. The range has the issue with the bullet, not case. In warm, dry areas such as California, it can be a fire hazard. This is generally due to the heavy concentration of steel in the jacket. Range restrictions: Some ranges don’t allow steel case ammo. This is due to the powder, not the case though. Some shooters’ note that steel case ammo can be dirtier than brass ammo. Studies have shown that it literally takes thousands of rounds for the additional wear to become apparent so the cost savings offset this. It’s just a fact that if you rub a harder metal against the same surface as a softer metal, the harder metal will wear that surface more quickly. This might be remedied by polishing the chamber.)ĭurability: Steel will be harder on parts such as extractors and barrels over time. (Note: When I say rough, I don’t necessarily mean visibly rough to the naked eye. 223 failed to show a measurable difference between steel and brass on the wear and tear of the chamber and barrel. On the other hand, studies have shown that over 10,000 rounds of. Steel does not contract as easily as brass, so if a chamber has any roughness or tool marks in it from the manufacturing process, the friction caused by the case not contracting enough - and the rough chamber - can cause poor extraction. The case must contract slightly to allow for easy extraction. When a cartridge is fired, the resulting pressure makes the case expand to the internal dimension of the chamber.
