Inconsistent Performance with Steel-Cased Ammo
If you own an AR15 rifle, you know that it is a versatile and reliable firearm that can handle a wide range of ammunition. However, you may have noticed that your AR15 does not always perform consistently with certain brands of ammo. One common issue that many AR15 owners encounter is inconsistent performance when using steel-cased ammunition.
Steel-cased ammo has become increasingly popular in recent years due to its affordability compared to brass-cased ammo. While steel-cased ammo can be a cost-effective option for target shooting and training, it may not always be the best choice for your AR15. The main reason for this is that steel-cased ammo can cause increased wear and tear on your rifle’s chamber and extractor.
Unlike brass-cased ammo, which is softer and more malleable, steel-cased ammo is harder and less flexible. This can lead to increased friction and heat buildup in the chamber, which can cause the steel casing to expand and stick in the chamber. This can result in extraction issues, such as failure to extract or stovepipes, which can affect the reliability and performance of your AR15.
In addition to extraction issues, steel-cased ammo can also cause increased wear on your rifle’s extractor. The harder steel casing can cause more stress on the extractor as it tries to pull the spent casing out of the chamber. Over time, this can lead to extractor wear and potentially even breakage, which can be costly to repair.
Another factor to consider when using steel-cased ammo in your AR15 is the quality of the ammunition itself. Steel-cased ammo is often manufactured using lower-quality components and may not be as consistent in terms of powder charge and bullet weight as brass-cased ammo. This can lead to variations in velocity and accuracy, which can affect your shooting performance.
If you are experiencing inconsistent performance with steel-cased ammo in your AR15, there are a few things you can try to improve reliability. First, make sure you are using high-quality steel-cased ammo from reputable manufacturers. Cheaper, lower-quality steel-cased ammo may be more prone to issues such as misfires and malfunctions.
You can also try cleaning and lubricating your rifle more frequently when using steel-cased ammo. The increased friction and heat generated by steel-cased ammo can cause more carbon buildup in your rifle’s chamber and bore, which can affect reliability. Regular cleaning and lubrication can help prevent these issues and keep your AR15 running smoothly.
In conclusion, while steel-cased ammo can be a cost-effective option for target shooting and training, it may not always be the best choice for your AR15. The increased wear and tear on your rifle’s chamber and extractor, as well as the potential for extraction issues and variations in performance, make steel-cased ammo less than ideal for some AR15 owners. If you are experiencing inconsistent performance with steel-cased ammo, consider switching to brass-cased ammo or trying different brands to see if that improves reliability.

Overpressure Issues with +P Ammunition
If you own an AR15 rifle, you know how important it is to choose the right ammunition for optimal performance. While most ammunition brands work well with this popular firearm, there are some instances where your AR15 might not like certain ammo brands. One common issue that can arise is overpressure problems with +P ammunition.
Overpressure occurs when the pressure inside the cartridge exceeds safe levels, causing potential damage to the firearm and posing a safety risk to the shooter. +P ammunition, also known as overpressure ammunition, is loaded to higher pressures than standard ammunition to achieve increased velocity and energy. While this can be beneficial for certain applications, it can also lead to problems when used in firearms not designed to handle the increased pressure.
One reason why your AR15 might not like certain ammo brands is that the rifle may not be rated for use with +P ammunition.
