Why is RayCasting not detecting humanoid most of the time?

I have been trying to make a gun using raycasting, but most of the time when i click on a humanoid the ray goes past it and hits the baseplate (Evident using print functions to find out where the ray is hitting) Please help!

local Player = game.Players.LocalPlayer
local mouse = Player:GetMouse()
local mousepostion = mouse.hit.p
local tip = script.Parent:WaitForChild("Tip")
local waits = false
local event = script.Parent.GunInfo:WaitForChild("FireEvent")
local damage = 35
local range = 350
local ignore = {Player.Character, script.Parent}

local function click()
    if waits then return end
    waits = true
    local orgin = tip.Position
    local direction = (mousepostion - orgin).Unit * range
    local rayresult = Ray.new(orgin, direction)

    if rayresult then
        local part, position = workspace:FindPartOnRayWithIgnoreList(rayresult, ignore)
        local humanoid = part.Parent:FindFirstChild("Humanoid")
        if not humanoid then
            humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
        end
        if humanoid then
            event:FireServer(humanoid, damage)
        else
        end
    end
    wait(.5)
    waits = false
end

script.Parent.Activated:Connect(click)
