Shared Parameters:
All sniper rifles do 70 base damage, regardless of range.
Equipping a silencer reduces the base damage to 50, regardless of range.
Stopping Power increases damage by 140% (1.4x).
Unique Body-Part Damage Multipliers:
Weapon - Head, Chest, Body, Limbs
Intervention - 1.5, 1.5, 1.1, 1.0
Barrett .50cal - 1.5, 1.5, 1.1, 1.0
WA2000 - 1.5, 1.5, 1.0, 1.0
M21 EBR - 1.5, 1.1, 1.0, 1.0
To get the damage output of each weapon, multiply the base damage (70 or 50) by the body-part area (1.5, 1.1 or 1.0). Multiply the result by 1.4 if Stopping Power is being used, and that should be your final total.
