Velocity Speed not hitting Object

Hello Developers, I have a problem with this script, let me explain it first, it fires at a moving block, bullets chase after the block but still miss, why is that? I will show the script.


local ReplicationStorage = game:GetService("ReplicatedStorage")
local Bullet = ReplicationStorage:WaitForChild("Bullet")

local Turret = script.Parent
local fireRate = 0
local bulletDamage = 1
local bulletSpeed = 150
local aggroDistance = 1000

while wait(fireRate) do	
	local target = nil
	for i, v in pairs(game.Workspace:GetChildren()) do
		local aa = game.Workspace.MovingModel.Platform
		if aa then
			if (aa.Position - Turret.Position).magnitude < aggroDistance then
				local bulletRay = Ray.new(Turret.Position, (aa.Position - Turret.Position).Unit * aggroDistance)
				local hit, position = game.Workspace:FindPartOnRayWithIgnoreList(bulletRay, {Turret})
				if hit == aa then
					target = aa
				
				end
			end
		end
	end
	
	if target then
		local aa = target
		Turret.CFrame = CFrame.new(Turret.Position, aa.Position)
		
		local newBullet = Bullet:Clone()
		newBullet.Position = Turret.Position
		newBullet.Parent = game.Workspace
		newBullet.Velocity = Turret.CFrame.LookVector * bulletSpeed * 8
		
		newBullet.Touched:Connect(function(objectHit)
			local aa = objectHit.Parent:FindFirstChild("Platform")
			if aa then
				print("hit")

			end
		end)
		
		
	end
end

Is the problem that there is a miscalculation or is the velocity speed to slow or…? Any help is appreciated.

Here is problem video, the bullets are not able to reach the moving block.
