So the sources you do come up with is a poorly done CNN news clip and a YouTube video of a dude drawing on a whiteboard? You also copy and pasted the wrong thing so the DoD piece just Isn’t there. I found one though https://www.wearethemighty.com/popular/762-to-5-56-rounds/#:~:text=always%20the%20case.-,America's%20adoption%20of%20the%205.56mm%20round%20and%20the%20service,general%20issue%20weapon%20and%20cartridge. And it has nothing to do with making bodies explode. Bullet fragmentation is reliant on factors like velocity and bullet construction, which varies. This is real life Bryan, not 40k. Debating gun control is fine just be honest about it.
