Stopping Power by Caliber Part 2

[LRRPF52]

To clarify, the explosive velocities are in reference to the heated gaseous expansion of the explosive reaction, while solid projectiles are limited to much slower velocities due to wind resistance and atmospheric pressure. I did read an interesting article in Small Arms Review that discussed how some of the most famous living small arms designers are just learning that lead-core projectiles morph into a plasma state when chamber pressure and heat are exerted on them. They said this accounts for much more barrel heating than they originally thought, combined with friction of the lead pushing outwards from within the confines of the projectile jacket. Adds a whole new understanding to the term..."hot lead".
