These 5.56mm NATO loads from Winchester should be at the top of your list for attending carbine classes, zeroing optics, and performing general range work. Winchester's name is synonymous with U.S. shooting culture due to their long tenure which spans over 150 years. During this time, they developed calibers and firearm actions which have shaped the face of shooting as we know today. As such, their products utilize modern components and undergo updated quality inspection methods.

Each of these rounds sports a 55-grain full metal jacket (FMJ) with a toothed cannelure, similar to the M193 specification. This cannelure ensures stable crimping which won't allow accuracy to degrade under recoil or rough handling. The FMJ bullet is seated into an annealed brass casing which flexes at the next for safety and reloadability. Each case has a non-corrosive Boxer primer inserted at its base for clean, reliable ignition with every shot. This particular lightweight load not only produces light perceived recoil but matches a wide spectrum of training loads for consistent performance with your sight settings.
