what helps the metal bullet go thoughft the foils
I'm not absolutely sure, but I'm confident a metal jacketed 38 special bullet will go through a human head at 300 ft.
Yes, several layers of drywall in fact if the bullet is FMJ ( full metal jacketed). Hollow points have less penetration in drywall and anything else for that matter.
Depends on the thickness of the platinum, the speed and weight of the bullet, and what the bullet is made of. A.50 caliber armor piercing bullet will shoot through some thicknesses of steel or concrete.
yes it go through wall
No it cant go through it.
It's quite likely, considering most 7.62mm cartridges are made to penetrate light armour (body armour and sheet metal).
Metal and Bullet...More info: Metal: fire & stone Bullet: Gunpowder & Metal
To get to the other side.
depends how thick the platinum is
I suppose that the causes are the high energy, density and speed.
gunpowder+ metal= bullet pow and metal + bullet= gun pow pow
