“I don’t know anyone over the age of 8 who would even think that a bullet would penetrate the exterior of a fuel tank like that”
Depends on caliber, bullet weight and velocity at impact.
A .308 at 30ft might get through...a .338 Lupua at 30 ft most certainly would.
5.56 at 700yds would barely pass through a bean can.
We had a water tank shot and the bullet penetrated the steel. Bullet recovered in bottom of tank was of the fifty cal variety. Sixty foot tank hit about the forty foot mark
