Call of Duty: Modern Warfare 2 weapon review. This was a direct request from one of my subscribers.
M21 is a 1 shot kill to the chest with Stopping Power, but not without. M21 has a base damage of 70 with a 1.1x damage multiplier to the chest. This is 77 damage without the 1.4x damage that is Stopping Power. 70 * 1.1 * 1.4 = 107.8 damage which translates into a kill. So everyone claiming that Stopping Power has no effect on the weapon system is sadly mistaken.
