The "hot lead" burning holes in plastic is preposterous nonsense.

Pistol and rifle brass gets very hot because it absorbs the heat of propellant gases (which is a good way to keep the chamber from over heating, since most of the heat gets tossed away each shot - one of the big challenges of caseless ammo).

Pistol and rifle bullets get hot because they are in contact with the propellant gases, and because of the friction of being formed to and pushed down the barrel.

Shot is insulated from the propellant gases by the plastic wad, and is protected from the barrel friction by the wad as well. The shot that landed on the moron-liar's kiddie pool was probably warmer when it landed then when it exited the muzzle, due to the effects of a few seconds in the sunshine.

I remember at Marine Corps ITS (Camp Geiger) we were told every night before we left the field to fire off all of our unused ammo. At that time (1980) our M-16s had full auto and we used to machine gun banana clip after banana clip of ammo to get rid of it. The barrels of our rifles actually turned orange from the heat.
