5.56×45mm is one of the most widely used rifle cartridges on earth — but what does its real lethality look like from point-blank distance out to 125 yards?
In this video, we break down the ballistic behavior of 5.56 at close and intermediate ranges, focusing on velocity loss, fragmentation thresholds, yaw behavior, and temporary/ permanent wound cavities.
We also examine how 5.56 performs when velocity drops below its fragmentation threshold (~2,700–2,500 fps depending on projectile type), and what this means for lethality inside 125 yards. This is a raw, practical, real-world look at what the round actually does — not theory, not myth.
Whether you’re military, LE, a hunter, a ballistic nerd, or a casual shooter, this video will give you a deeper understanding of how 5.56 actually wounds, what matters, and why distance makes such a difference.
