re: Spinoff Thread -- Handgun Stopping Power

Generally the faster a bullet travels, the more it expands. And the more it expands, the more energy it takes to push that larger surface area into the object. I often use the analogy of pushing a map pin into sheetrock vs. pushing a railroad spike into sheetrock. The spike, having a larger diameter, requires more force/energy to shove it into the drywall.

Good information that my EIT brain can wrap around.

But that definitely makes sense. I think I've seen a few tests comparing Speer's short barrel versions to their standard versions with little difference in performance. But since the Gold Dot is still one of the best out there, I doubt it matters much.
