velocity not working with raycasting?

I'm trying to make a gun script but I got confused so I copy pasted a script from the wiki with the intent to modify it to my needs. I do understand more about raycasting after I've done this but i'm stuck as i'm trying to make a bullet move towards the location, not teleport to it. It does damage the player but the bullet is nowhere to be seen.

local tool = script.Parent
local player = game:GetService("Players").LocalPlayer
 
tool.Equipped:connect(function(mouse)
	print("MEN!")
 
	mouse.Button1Down:connect(function()
		
		local ray = Ray.new(tool.muzzle.CFrame.p, (mouse.Hit.p - tool.muzzle.CFrame.p).unit * 300)
	
		local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)
 
		local beam = Instance.new("Part", workspace)
		beam.BrickColor = BrickColor.new("Cool yellow")
		beam.FormFactor = "Custom"
		beam.Material = "Neon"
		beam.Transparency = 0.25
		beam.Anchored = true
		beam.Locked = true
		beam.CanCollide = false
		
		
		local distance = (tool.muzzle.CFrame.p - position).magnitude
		beam.Size = Vector3.new(0.3, 0.3, 1)
		
		beam.Velocity = distance * Vector3.new(.1,.1,.1)
 		
		local light = Instance.new("SpotLight")
		light.Parent = beam 
		
		game:GetService("Debris"):AddItem(beam, 60)
 
		if part then
			local humanoid = part.Parent:FindFirstChild("Humanoid")
 
			if not humanoid then
				humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
			end
 
			if humanoid then
				humanoid:TakeDamage(30)
			end
		end
	end)
end)

Original script in WIKI https://www.robloxdev.com/articles/Making-a-ray-casting-laser-gun-in-Roblox

Why is it that you want to use velocity? On line 31 You’re also having the beam last for 60secs? Maybe that was on purpose but it seems rather long for a projectile You’d have to change your velocity line 26 to...

beam.CFrame = CFrame.new(tool.Muzzle.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)

If you want to use Velocity, here is a good example script you’d put in a projectile part...

-- Put this Script in a Part, preferably bullet-shaped :)
local part = script.Parent
part.Shape = Enum.PartType.Ball
part.Size = Vector3.new(2, 2, 2)
part.BrickColor = BrickColor.new("Really black")
part.CanCollide = false
 
-- Settings for the projectile's path!
local startPoint = Vector3.new(0, 50, 0)
local targetPoint = Vector3.new(50, 100, 0)
local travelTime = 1
local antiGravity = .5
 
-- Anti-gravity effect: add a BodyForce to counter gravity
local bf = Instance.new("BodyForce")
bf.Force = Vector3.new(0, workspace.Gravity * part:GetMass() * antiGravity, 0)
bf.Parent = part
 
-- Add a trail to two attachments
local a0 = Instance.new("Attachment", part)
a0.Position = Vector3.new(1, 0, 0)
local a1 = Instance.new("Attachment", part)
a1.Position = Vector3.new(-1, 0, 0)
local trail = Instance.new("Trail", part)
trail.Attachment0 = a0
trail.Attachment1 = a1
trail.FaceCamera = true
trail.Transparency = NumberSequence.new({
	NumberSequenceKeypoint.new(0, 0),
	NumberSequenceKeypoint.new(1, 1)
})
trail.Lifetime = .35
 
local function fire(startPoint, targetPoint)	
	-- Calculate how far we have to travel
	local distance = (targetPoint - startPoint).magnitude
	-- Since speed = displacement / time, our speed is:
	local speed = distance / travelTime
	-- Position our part at the start, pointing to the target
	part.CFrame = CFrame.new(startPoint, targetPoint)
	-- Shoot the part
	part.Velocity = part.CFrame.lookVector * speed
end
 
-- Repeatedly fire the projectile
while true do
	fire(startPoint, targetPoint)
	wait(travelTime)
end
