It all depends on the caliber and if it is fired out of a handgun or rifle. Range of a few hundred meters to a couple of thousand possible.
No trouble at all.
Depending on the bullet, 9mm goes slower than it, but a 45-50cal.
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.
Accurately- about 50 yards. How far COULD it go- no accuracy, fired at about a 45 degree angle? About 1500-2000 yards, depending on the gun.
To many variables. Depends on caliber of bullet, type of dirt, type of ammo, distance from gun to ground,etc...
If you want to stop further damage, you go to the hospital.
In excess of 1.5 miles.
