Why does not the variable Remove the Bullets When Reloaded?

So i am making a gun. Basically im working right now on reload stuff. its done but When it reloaded i can shoot forever without More reloading. Heres the script:

wait(3)
local Humanoid = game.Players.LocalPlayer.Character.Humanoid
local ShootAnimation = Instance.new("Animation")
local ReloadAnimation = Instance.new("Animation")
ReloadAnimation.AnimationId = "rbxassetid://5593968248"
local ReloadAnimationTrack = Humanoid:LoadAnimation(ReloadAnimation)

ShootAnimation.AnimationId = "rbxassetid://5593333395"

local ShootAnimationTrack = Humanoid:LoadAnimation(ShootAnimation)
bullets = 9

local mouse = game.Players.LocalPlayer:GetMouse()
local Handle = script.Parent.Handle
local Gun = script.Parent
ReloadAnimationTrack.Looped = false
function Reload() -- Somewhere on this function stuff?
    print("Reloading...")
    ReloadAnimationTrack:Play()
    wait(ReloadAnimationTrack.Stopped)
    return
end


warn('The Tool M9 Is Officialy made by HKprogram To Easyjet Security')
Gun.Activated:Connect(function()
    if mouse.Target.Parent:FindFirstChild("Humanoid") then -- Clicked a type of humanoid
        if bullets == 0 then
            Reload()
        end
        bullets = bullets - 1 -- When you see this. Its Removing bullets
        ShootAnimationTrack:Play()
        mouse.Target.Parent.Humanoid:TakeDamage(30) -- Damage 50 taken 
        print("Target: "..mouse.Target.Name)
    elseif mouse.Target.Parent:FindFirstChild("Head") then
        if bullets == 0 then
            Reload()
        end
        ShootAnimationTrack:Play()
        mouse.Target.Parent.Humanoid:TakeDamage(100)
        bullets = bullets - 1
        print("Target: "..mouse.Target.Name)
    else
        if bullets == 0 then
            Reload()
        end
        bullets = bullets - 1
        ShootAnimationTrack:Play()
        print("Target: "..mouse.Target.Name)
    end
end)

Anyone know the problem? theres no errors in script
