Product Overview

Winchester's 5.56x45mm NATO reloading bullets are engineered for shooters who want to build precision ammunition from the ground up. These .224-caliber, 55-grain full metal jacket boat-tail (FMJBT) projectiles are purpose-built components for handloaders working with centerfire rifle loads—whether you're assembling match-grade rounds for the range, training ammunition for your AR platform, or field loads for hunting. Winchester's reputation for consistency makes these bullets a reliable choice when you control every variable in the cartridge.

The boat-tail design improves ballistic efficiency, reducing drag and helping maintain velocity downrange compared to flat-base alternatives. Full metal jacket construction offers reliable feeding and performance across a wide range of firearms and shooting conditions. At 55 grains, this weight is a classic choice for 5.56 NATO, offering a proven balance of velocity, energy, and handling characteristics in modern sporting rifles and AR-15s.

Each box contains 500 bullets, giving you bulk quantity for serious reloaders who shoot regularly or work up multiple loads. Winchester's manufacturing consistency means you can focus on perfecting your powder charge, primer selection, and seating depth rather than chasing wild variations between bullets. This is component-level quality—the foundation of handloaded ammunition that performs exactly as you intend.
