SWEP.HeadshotMultiplier isnt working

[getyadogsoffm]

The base is 14 damage, but headshots do 44 damage no matter what i set the multiplier to. Other guns don't appear to have this happening, just this mac10

   AddCSLuaFile( "shared.lua" )

Because it's being overwritten by SWEP:GetHeadshotMultiplier later in the file. If you want it to be a flat 2.0 multiplier, just delete the whole GetHeadshotMultiplier function.
