PMC X-Tac 5.56x45mm NATO Ammunition 55 Grain Full Metal Jacket - 5.56X
PMC X-Tac 5.56x45mm NATO Ammunition (SKU: 5.56X) is purpose-built for shooters who value dependability and precision every time they pull the trigger. Manufactured by PMC—a brand with a solid reputation for delivering high-quality, military-spec ammunition—each round features a 55-grain Full Metal Jacket (FMJ) bullet that excels in consistency, feeding, and overall performance. Whether you’re heading to the range for recreational target practice, honing your skills in competitive shooting environments, or running drills in tactical training scenarios, the X-Tac line is engineered to stand up to rigorous demands without sacrificing accuracy.
At the heart of this ammunition’s reliability is its robust brass casing and non-corrosive Boxer primer. Not only does this combination support smoother cycling through semi-auto platforms, but it also makes the rounds reloadable—an added bonus for high-volume shooters looking to maximize value. Tested to NATO specifications, PMC X-Tac 5.56x45mm rounds reach a muzzle velocity of approximately 3,270 fps when fired from a 20-inch barrel, delivering both the flat trajectories and the terminal performance enthusiasts seek. With consistent velocity, manageable recoil, and minimal barrel fouling, these rounds make a perfect match for a wide variety of 5.56 NATO firearms. If reliability, consistent shot placement, and high-volume practicality are top priorities, PMC X-Tac is a premier choice for your next trip to the range.

Overview
PMC X-Tac 5.56x45mm NATO Ammunition is crafted for shooters who demand precision and reliability from their rounds. Whether used for target practice or competitive shooting, this ammunition delivers consistent performance and tight groupings. Its design caters to military and civilian shooters who require ammunition that performs flawlessly under various conditions. The Full Metal Jacket bullet enhances the ballistics, ensuring minimal expansion upon impact, making it suitable for training environments where exact results are required.
History and Development
PMC (Precision Made Cartridges) traces its roots to the Poongsan Corporation of South Korea, an established manufacturer of munitions for both military and civilian markets. Over the decades, Poongsan leveraged its extensive experience supplying the Republic of Korea Armed Forces to develop robust and reliable ammunition that could meet rigorous military standards. Recognizing a growing global demand for mil-spec quality in civilian shooting sports, PMC introduced the “X-Tac” line to bring that same level of reliability and consistency to the commercial market.
The 5.56x45mm NATO offering within the X-Tac series was designed with input from professional shooters, military personnel, and avid sports shooters who sought dependable performance under various conditions. PMC invested heavily in research, testing, and quality control to ensure that each round adheres to exacting NATO specifications—resulting in consistent velocities, reliable cycling, and impressive accuracy. Over time, X-Tac has gained a strong following among AR-15 enthusiasts, competitive shooters, and others seeking a trustworthy training round that also mirrors many of the ballistic characteristics of a true duty load.
Today, PMC continues to refine its production processes and maintain strict quality checks, positioning the X-Tac brand as a staple for those who value top-tier consistency, reloadable brass casings, and adherence to NATO standards. This long-term commitment to precision, reliability, and innovation has solidified PMC’s reputation as one of the industry’s most dependable sources for 5.56x45mm ammunition.
Common Questions and FAQs
- What’s the difference between 5.56x45mm NATO and .223 Remington, and can I fire this ammo in a .223 chamber?
While 5.56 NATO and .223 Remington cartridges have nearly identical external dimensions, 5.56 NATO is loaded to higher pressures and often has a longer throat (leade). As a result, firing 5.56 ammo in a .223 chamber can potentially create higher-than-recommended pressures. If your rifle is chambered specifically for .223, consult your firearm manufacturer before using 5.56 ammo. Many modern firearms marked 5.56/.223 can safely accommodate both.
- Is this ammunition safe and suitable for civilian use?
Yes. PMC X-Tac 5.56x45mm NATO Ammunition, while meeting NATO specifications, is readily available to civilians for activities like target practice, competitions, and training drills. Always be sure to follow local regulations regarding ammunition usage or restrictions.
- Why choose a 55-grain Full Metal Jacket bullet for target practice?
The 55-grain FMJ bullet feeds reliably, maintains consistent trajectories, and reduces barrel fouling, making it ideal for high-volume practice. FMJ rounds are also cost-effective compared to specialized bullets—perfect for spending extended time at the range.
- Does this bullet have a steel core, and will it attract a magnet?
PMC X-Tac 5.56 typically features a lead core with a copper jacket, not a steel core. Thus, it generally does not attract a magnet. However, for compliance with range rules and local regulations, it’s best to confirm with the manufacturer or perform a magnet test if needed.
- How does barrel length affect muzzle velocity with this ammunition?
The listed muzzle velocity of approximately 3,270 fps is measured from a 20-inch test barrel. Shorter barrels will produce slightly lower velocities due to reduced pressure and burn time, whereas a longer barrel may see a slight velocity boost. Most recreational or competitive shooters find these differences negligible for typical shooting applications.
- Is this ammo reloadable, and how many times can the brass be reused?
Yes. PMC X-Tac ammo features brass casings with a non-corrosive Boxer primer, making it reloadable. The number of times you can safely reload a casing depends on factors like chamber pressure, resizing methods, and overall handling. With proper care, multiple reloads per case are common.
- Are there bulk purchase options and free shipping deals available?
Many vendors offer this ammunition in bulk (cases of 500 or 1,000 rounds), which can reduce the per-round cost. Some retailers also offer free shipping promotions for large orders. Check current deals or subscribe to newsletters to take advantage of these offers.
- What is the best way to store this ammunition?
Store PMC X-Tac 5.56 ammo in a cool, dry place, such as an ammo can or sealed container with desiccant packets. Avoid extreme temperature and humidity fluctuations to maintain optimal performance and shelf life.
- Can I use this ammo for small-game or varmint hunting?
While you technically can, a 55-grain FMJ bullet is not ideal for hunting because it doesn’t expand upon impact. If you’re hunting small game or varmints, consider hollow point or soft point rounds designed for controlled expansion and terminal performance.
- Which rifle barrel twist rate works best for this 55-grain bullet?
Most AR-15 platforms with a 1:7, 1:8, or 1:9 twist rate can stabilize 55-grain projectiles effectively. A 1:9 twist is often recommended for strictly 55-grain usage, while 1:7 or 1:8 allows for a broader weight range, including heavier bullets up to 77 grains.
