Casted ray isn't always picking up that it has connected with a player?

Currently I am scripting a weapons handler script for a game I am working on. The guns shoot out a beam, which travels a set distance and lingers for a very short period of time. When this beam is fired, a ray is also fired too, that follows the beam, to detect if a character is hit to then deal damage. However, it doesn't always deal damage. It used to work every time when the ray was drawn between the targetlocation and the handle, however, the script was modified have spray, and since then the rays have been inconsistent, even with the weapon that has no spray. This is the script:

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
						local Distance = (TargetLocation - Handle.Position).magnitude
						if Distance >= relevantData.RANGE then
							Distance = relevantData.RANGE
						end
						Distance = Distance + 5
						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
						game.Debris:AddItem(Beam, 0.1)

						local NewRay = RaycastParams.new()
						local RayDirection = Beam.CFrame.LookVector * Distance

						NewRay.FilterDescendantsInstances = {Player.Character}

						local Result = workspace:Raycast(Handle.Position, RayDirection, NewRay)

						if Result then
							if Result.Instance then

								local humanoid = Result.Instance.Parent:FindFirstChild("Humanoid") or Result.Instance.Parent.Parent:FindFirstChild("Humanoid")
								if humanoid then
									humanoid.Health -= relevantData.DMG
								end
							end
						end
						if relevantData.DELAY ~= 0 then
							wait(relevantData.DELAY)
						end
					end
				end


			end
		end
	end

end)

If anyone knows why it isn't always damaging the player, then any pointers in the right direction would be appreciated
