Winchester Ammo WM193150 USA5.56x45mm NATO 55 gr 3270 fps FMJ150 Bx/4 Cs (Value Pack)

Winchester USA 5.56x45mm NATO ammunition in this 150-round value pack delivers straightforward, reliable performance for shooters who want effective range ammo without the premium price tag. Built on Winchester's reputation for consistency, these rounds pair a 55-grain full metal jacket bullet with brass cases and a modern powder formulation—the kind of combination that's kept Winchester in shooters' ammo cans for generations. At 3270 fps, you get predictable ballistics suitable for target work, practice, and general rifle use across modern sporting rifles and military-pattern carbines.

The full metal jacket design is the workhorse of range and training ammunition: it feeds reliably through most semi-automatic rifles, shoots clean enough for indoor ranges (thanks to modern propellant technology that reduces barrel fouling), and delivers the shot-to-shot consistency you expect when you're zeroing optics, honing technique, or simply putting rounds downrange. The brass cases are reloadable, which matters to handloaders looking to extend the value of bulk ammo buys. This isn't match-grade ammunition, and it doesn't pretend to be—it's built for volume shooters who demand dependable function and decent accuracy without paying for precision-rifle tolerances.

The 150-round configuration (150 Bx/4 Cs) breaks into four 50-round boxes, giving you flexibility: grab one for a short range session or stock all four for a dedicated practice day. That structure also makes it easier to track inventory and rotate stock in your ammunition storage. Whether you're maintaining zero on a duty or hunting rifle, breaking in a new platform, or running drills at an indoor range, Winchester USA white box has earned its reputation as a dependable baseline—affordable enough to shoot regularly, consistent enough to trust your fundamentals against.
