Ammo

In Tarkov the ammo matters more than the gun. Armour has a class from 1 to 6. Whether a bullet goes through depends mostly on its penetration value against that class.

A common community rule of thumb: a round beats armour reliably when its penetration is at least about 10 × the armour class (so 40+ for class 4). The colour tiers below use that rule. It's a rough guide, not the exact formula: armour durability and the armour material change the odds too.

Damage is what you do to flesh; armour damage is how fast it wears armour down. For shotgun shells, damage is per shell (all pellets together).
