Description
The PMC X-Tac 556 NATO 55gr FMJBT load, item 556X, is a 20 round box of 5.56x45mm NATO ammunition from PMC, loaded with a 55 grain FMJ-BT bullet.
PMC X-Tac 556 NATO 55gr FMJBT Overview
PMC X-Tac is loaded to military specifications for shooters who want ammunition that matches what military and law enforcement agencies use in training and service. It is a popular choice for carbine courses, high-volume training and stocking up, with brass cases and sealed primers built for dependable function.
Bullet Design
The full metal jacket boat tail bullet has a tapered base that reduces drag, helping it hold velocity and resist wind drift downrange. The copper jacket keeps lead fouling down and feeds smoothly.
Intended Use
X-Tac is designed for training and practice that mirrors military ammunition, so point of impact and function closely match issue loads.
Firearm Compatibility
This ammunition is made for rifles and pistols chambered in 5.56x45mm NATO, including most AR-15 rifles and carbines with 5.56 or 223 Wylde chambers. Do not fire 5.56 NATO ammunition in a firearm marked only for 223 Remington, because 5.56 loads can run at higher pressure.
About PMC
PMC, short for Precision Made Cartridges, has built ammunition for decades and is based in Houston, Texas. Its lineup covers practice, training, match and hunting loads for handguns and rifles, with a focus on consistent, dependable performance at a fair price.
Recoil and Shootability
Recoil from the 5.56 NATO is light in a carbine or rifle, so follow-up shots are fast and long training sessions stay comfortable.
Choosing This Load
X-Tac makes sense for training that should match issue ammunition and for building a supply of dependable rifle ammunition. Its brass cases and consistent loading make it a good choice for carbine classes, drills and long days at the range.
About the Cartridge
The 5.56x45mm NATO is the standard service cartridge of the US military and many allied forces. Its light recoil, flat trajectory and the popularity of the AR-15 have made it one of the most widely shot rifle cartridges in the world.
Brass Cases
PMC loads its centerfire ammunition in boxer-primed brass cases. Brass extracts reliably, resists corrosion and can be collected and reloaded by handloaders, which adds value to every box you shoot. Collect your fired cases at the range if you reload, and sort them by headstamp and caliber for easy processing later.
Range Safety
Always wear eye and ear protection, confirm the correct ammunition for your firearm before loading, and keep different calibers separated in your range bag. Treat every firearm as loaded, and know your target and what is beyond it.
Practice and Testing
Shoot a few groups with this load to learn where it prints in your firearm, and check function with full and partly loaded magazines. Keeping a consistent supply of the same load makes it easier to track your progress over time.
Storage and Care
Store ammunition in a cool, dry place in its original boxes, away from solvents and lubricants that can contaminate primers. Inspect rounds before loading, and set aside any with dents, loose bullets or corrosion.
