Details
When we say this ammo is basic, we’re not saying it’s poorly made. It’s just loaded with the 5.56’s most common weight bullet, and it’s a simple full metal jacket at that. Winchester’s FMJ is a simple combination of lead core and copper alloy jacket, and together its components are incapable of drawing a magnet. Although ammo exactly like this is commonly used for combat, an expanding bullet like a JHP, soft point or polymer tip is far more preferable for home defense.
This is new ammo: non-corrosive, clean-burning, Boxer-primed and reloadable. You may already have noticed that its brass cases are gray around their shoulders. That discoloration is merely the byproduct of the annealing process which strengthens brass. Winchester doesn’t polish the cases to make them prettier, but they function just as reliably as the shiniest cases in the world.
