How do I CFrame projectiles for a turret ?

So far Ive made a script that shoots a ball when ever it detects a part or a human etc but I don't know how to make a CFrame of the bullet moving from the start position to the hit position.

local ray = Ray.new(script.Parent.Position,Vector3.new(0,0,-40))
local test = game.Workspace.test
local Debris = game:GetService('Debris')


while wait(1)do
    local hit,position = workspace:FindPartOnRayWithIgnoreList(ray,{script.Parent})
    if hit then 
        print(hit.Name)

        local o = Instance.new("Part",game.workspace)
        o.Anchored = false
        o.CFrame = CFrame.new(position)
        o.Size = Vector3.new(1,1,1)
        o.Shape = "Ball"
        o.BrickColor = BrickColor.new("Bright green")
        o.Material = "Neon"
        o.Parent = test




        Debris:AddItem(o,2)-- It will delete the projectile after 2 seconds
    end
end

Im quite new to coding and i'm Interested to learn more.
