Ok CoSo smarties. I’m curious about something I saw but don’t understand the point and don’t trust google.
Why would a bullet be thick, squat, and covered in copper?
Seems not aerodynamic and not twisty/fragmenting to cause a lot of damage. So short distance with more force?

"thick, squat" sounds like you're describing 45acp. A caliber that I have (surprise) a more than passing expertise with.
You're describing what's called a "full metal jacket" round (regardless of caliber). FMJ is primarily for any and all higher velocity ammo as it doesn't deform as quickly as base lead does on firing or impact.
Below are FMJ 45acp cartridges (left) and bullets (right).
