So I have a flintlock for my game which uses raycasting and I want to use FindPartOnRay to basically have a bullet mark whenever I shoot, it works but the issue is if the player is moving it has a higher chance of never reaching a part. Also sometimes it's left in the air due to the way it's coded but I don't know how to change it to ignore the player and find out if there's a part where it's hitting..

Here's my script lines 45-52 are the main one's I'm looking at just posted the whole thing to give people a better idea of what's going on..

--Configuration
local reloadtime = 1 -- time in seconds
local damage = 100 -- damage 1:1
local flash = true -- set true if you want pointlight to be enabled
local tk = false -- set true if you want to be able to kill teammates
local Distance = 75 -- Calculated in studs
local brickColor = BrickColor.new("Dirt brown")






--Variables
local version = "1.4.0 Fixed issues with configuration's Config will now be found within the gun script."
local tool = script.Parent
local player = game:GetService("Players").LocalPlayer
local halt = 0
local col = script.Parent:FindFirstChild("teamColor")

print(version)
tool.Equipped:connect(function(mouse)
	print("Tool equipped!")
 	script.Parent.teamColor.Value = player.TeamColor
	mouse.Button1Down:connect(function()
		if halt == 1 then
			print'reloading'
		else
			halt = 1
		print("Mouse pressed!")
		local ray = Ray.new(tool.Handle.CFrame.p, (mouse.Hit.p - tool.Handle.CFrame.p).unit * 300)
		local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)
 		script.Parent.Handle.PewPew:Play()
		local beam = Instance.new("Part", workspace)
		beam.BrickColor = BrickColor.new("Black")
		beam.FormFactor = "Custom"
		beam.Material = "Plastic"
		beam.Transparency = 0.25
		beam.Anchored = true
		beam.Locked = true
		beam.CanCollide = false
		
	local distance = Distance
	
		beam.Size = Vector3.new(0.3, 0.3, distance)
		beam.CFrame = CFrame.new(tool.Handle.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)
		local hit, position = game.Workspace:FindPartOnRay(ray, player.Character)
		local p = Instance.new("Part", workspace)
		p.Anchored = true
		p.CanCollide = false
		p.BrickColor = BrickColor.new("Black")
		p.Transparency = 0
		p.FormFactor = "Custom"
		p.Size = Vector3.new(.2,.2,.2)
		p.CFrame = CFrame.new(position)
		local d = script.Parent.SmokePartHandler:Clone()
		d.Parent = p
		d.Disabled = false
		
		if flash == true then
			script.Parent.Flash.Flash.Enabled = true
			script.Parent.Flash.Smoke.Enabled = true
			wait(0.1)
			script.Parent.Flash.Flash.Enabled = false
			script.Parent.Flash.Smoke.Enabled = false
		end	
		
		game:GetService("Debris"):AddItem(beam, 0.1)

		if part then
			local humanoid = part.Parent:FindFirstChild("Humanoid")
 
			if not humanoid then
				humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
			end
 
			if humanoid then
					if tk == true then
				if game.Players:FindFirstChild(part.Parent.Name).TeamColor.Name ~= script.Parent.teamColor.Value then
				humanoid:TakeDamage(damage)
				else
				humanoid:TakeDamage(damage)
					end
				end
			end
		end
			wait(reloadtime)
			halt = 0
		end
	end)
end)
