How to tween in a certain direction?

Here is my code for a gun I want to tween the bullet to where it is facing. Anybody know how?

local player = game:GetService("Players").LocalPlayer
local mouse = player:GetMouse()
local tool = script.Parent

tool.Activated:Connect(function()
	--Set Up
	local bullet = Instance.new("Part")
	--Size
	bullet.Size = Vector3.new(0.27,0.25,1.49)
	--Anchored
	bullet.Anchored = true
	--Can/Can Not Collide
	bullet.CanCollide = false
	--Color
	bullet.BrickColor = BrickColor.new("Really red")
	--Matirial
	bullet.Material = Enum.Material.Neon
	--Parent
	bullet.Parent = workspace
	--Positon
	bullet.Position = tool.Handle.Position + Vector3.new(0,0.5,0)
	--Angle
	bullet.CFrame = CFrame.new(bullet.CFrame.p, mouse.Hit.p)
	
	--Movement
	local TweenService = game:GetService("TweenService")

	local info = TweenInfo.new(3, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut, 0, false, 0)
	
	TweenService:Create(bullet, info, {Position = bullet.Position + Vector3.new(0,0,100)}):Play()
	
end)
