YouTube gunners usually simplify, despite given granted better knowledge, that topic down to sub and super referring to subsonic or supersonic projectile speeds of the ammo.
Velocity of ammo can quickly double as this chart shows.
Simplified, that is also double the impact of the gun than.
Usually the difference derives from different propellants used, which is simplified speaking the used gun powder.
As much as Black Powder is less dangerous than Semtex gun powder strength may vary.
On top precision is very important of both gun and projectile to cause damage beside the material fired.
Copper head projectiles are less dangerous than forming but dense and heavier lead against a bullet proof vest in terms of penetration, but not damage done to the human target.
A lead projectile can turn into a long needle like object over distance by in high speeds heated up by a strong propellant and long barrel to penetrate, while a copper head hits a harder vest inlay to than deform into an even bigger diameter waisting it's penetration energy.
But if hiting the human tissue one would create a small tiny cut sliding through the body and the other rip a huge hole.
The knick named Cop Killer ammo was a standard size 9mil, but loaded with high end propellant and a tool steel level hardened and not round but pointing metal head that did both break a weak wrisk and penetrate every LAPD vest granted creating the need to also rework the gun or go back to a classic Peacemaker Revolver Wild Wild West style.
And blanks, some come to a fire fight with blanks... hot choclat coated sweet talkers
