Do silencers reduce the amount of damage that guns do?
Solution 1:
According to The Call of Duty Wiki
As a disadvantage, the Silencer either reduces the range at which weapons do their maximum damage, damage of the weapon as a whole, or the damage done by the weapon at its longest range depending on what weapon the Silencer is used with.
In Call of Duty Ghosts Silencer reduces the range in guns which means that the drop-off damage is reduces. To most guns this is by -25% range.
For Example:
According to Symthic:
The damage of the Honey Badger drops off to 20 at 33 meters without a silencer.
With a silencer and the -25% range reduction the dropoff instead of 33 meters turns to 24.75 meters. Which will change the amount of shots from 4 to 5 between 24.75 - 33 meters.
To many it would seem like a damage reduction; because it is but it only reduce the range. The gun will never drop below 20 damage per shot.
Solution 2:
The silencer only lowers the Max effective range, so it does less damage at longer ranges. But it hardly changes any of the Sniper Rifles Max Effective Range.
