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)
