CFrame positioning randomness and multiple parts at once for a "fireball"?

2 questions So i'm working on a machine gun but i want to to shoot out multiple bullets at once and or have a spraying effect that shoots out 1 bullet but the CFrame positions are random. Heres my script

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local Ammo = 1
--CUSTOMIZE--
Mouse.Button1Down:connect(function()
        if Ammo > 0 then
            local x = Instance.new("Part", workspace)
            Ammo = Ammo-1
            x.Shape = "Block"
            x.CanCollide = false
            x.Size = Vector3.new(0.5, 0.5, 1.5)
            x.BrickColor = BrickColor.new("Bright yellow")
            x.TopSurface = "Smooth"
            x.BottomSurface = "Smooth"
            x.CFrame = Player.Character.Torso.CFrame * CFrame.new(0,0,-3)


--DAMAGE--      
            x.Touched:connect(function(hit)
                if hit.Parent:FindFirstChild("Humanoid") ~= nil then
                    hit.Parent.Humanoid:TakeDamage(12.5)
            x:remove()
                end
            end)
--VELOCITY--
local       v = Instance.new("BodyVelocity", x)
            v.Velocity = Player.Character.Torso.CFrame.lookVector * 150

            v.maxForce = Vector3.new(math.huge, math.huge, math.huge)           

            x.Parent = workspace
            wait(1.25)

            x:remove()

        end
end)
--AMMO--
while true do
    if Ammo == 0 then
        wait(0.1)
        Ammo = 1
        end
        wait(0.1)
end

For my first question about shooting multiple parts at once, i duplicated the script and it works but im wondering if theres a less messy way of doing it without having so many scripts

And for my 2nd question about the spraying, i tried using or but that doesn't work
