Help with Roblox Bullet movement and hit detection?

So I've been spending a bit of time trying to make some bullets to work for the guns used in a game I'm helping out with... After some issues Cframe's not being the greatest, and with Tween making it smoother (not actually implemented as of yet as I haven't worked with the service) but not fixing the issue I was looking to explore other options. It's fairly common knowledge that 2 anchored objects cannot touch. The issue is, both objects have to be anchored, as one is walls, and if the bullets are not anchored, they go under the effect of gravity far too quick. So a simple solution I have thought of is applying a body force to negate gravity. However when shooting at angles up or down, I'm not sure how realistic this is.

That became an option due to the issues I had with using :GetTouchingParts(), as the bullets start by touching the gun's handle, and then may make contact with each other as there is a gun with a multi-shot spray, and I've not really seen a good way to filter out certain touching parts.

The other option there is, is using FastCast. From reading the site and looking at the module scripts it seems really great, however being fairly new to scripting, is incredibly overwhelming and I have absolutely no idea where to start.

What I'd like to know is whether the bodyforce to negate gravity is actually feasible, and by combining that with tweening will work well enough (the max server size is only 6 players so it won't be overwhelmed with bullets), or whether changing to fast cast is really the only way forwards. And if that is the case, any pointers on how to implement it would be extremely helpful.

Here is the code for when the gun is fired and a bullet is created (which deals with getting the bullet data for that gun and also directing the offset for the spray of the bullets:

local GunData = require(game.ReplicatedStorage.GunData)
local rep = 1
game.ReplicatedStorage.ShootGun.OnServerEvent:Connect(function(Player, TargetLocation, Handle)
	if Player.Character == nil then
		return
	end

	if Handle then
		local Tool = Handle.Parent
		if Tool:IsA("Tool")then
			if Tool.Parent == Player.Character then
				local relevantData = GunData[Tool.Name]
				if relevantData ~= nil then
					for count = 1,relevantData.REP do
						Handle.Sound:Play()

						local Beam = Instance.new("Part", workspace)
						Beam.Color = relevantData.COLOR
						Beam.FormFactor = "Custom"
						Beam.Transparency = 0.25
						Beam.Material = "Neon"
						Beam.Anchored = true
						Beam.CanCollide = false
						Beam.Name = "Bullet"
						Beam:SetAttribute("Speed",relevantData.SPEED)
						Beam:SetAttribute("Damage",relevantData.DMG)
						Beam.CanTouch = true
						Beam:SetAttribute("Shooter",Tool.Parent.Name)
						
						local Distance = (TargetLocation - Handle.Position).magnitude
						if Distance >= relevantData.RANGE then
							Distance = relevantData.RANGE
						end
						local NewAngle = CFrame.Angles(math.rad(math.random(-relevantData.ANGLE,relevantData.ANGLE)),math.rad(math.random(-relevantData.ANGLE,relevantData.ANGLE)),math.rad(math.random(-relevantData.ANGLE,relevantData.ANGLE)))
						Beam.Size = Vector3.new(relevantData.WIDTH, relevantData.WIDTH, Distance)
						Beam.CFrame = CFrame.new(Handle.Position, TargetLocation) * CFrame.new(0, 0, -Distance/2)
						local offset = Handle.CFrame:Inverse()*Beam.CFrame
						local handleStartCFrame = Handle.CFrame
						local newCFrame = handleStartCFrame*NewAngle
						Beam.CFrame = newCFrame*offset
						
						
						local moveBullets = script.bulletMovement:Clone()
						moveBullets.Parent = Beam
						local hitBullets = script.hitDetection:Clone()
						hitBullets.Parent = Beam
						Beam.Parent = game.Workspace["Futuristic Tycoon"].Bullets						


						if relevantData.DELAY ~= 0 then
							wait(relevantData.DELAY)
						end
					end
				end


			end
		end
	end

end)

Here's the movement script:

scrpar = script.Parent
speed = scrpar:GetAttribute("Speed")
while true do
	if scrpar.Name == "Bullet" then
		wait()
		for count = 1,20 do
			scrpar.CFrame = scrpar.CFrame + scrpar.CFrame.lookVector * speed
			wait()
		end
		scrpar:Destroy()
	end
end

Finally, the hit detection... only detects humanoids for now as they are not anchored:

local Players = game:GetService("Players")
local scrpar = script.Parent
local damage = scrpar:GetAttribute("Damage")
local shooter = scrpar:GetAttribute("Shooter")
scrpar.Touched:Connect(function(hit)
	print("touched")
	local humanoid = hit.Parent:FindFirstChild("Humanoid") or hit.Parent.Parent:FindFirstChild("Humanoid")
	if humanoid then
		local player = Players:GetPlayerFromCharacter(humanoid.Parent).Name
		if player ~= shooter then
			humanoid.Health -= damage
			scrpar:Destroy()
		end
	end
end)
