The chuck will secure the chamber end of the barrel. To index (or turn) the barrel I will be using a 10″ rotary table equipped with an 8″ three jaw chuck and tail stock. There are plenty of online resources available to help you with the math.

If you need help with calculating how to index your ports, google “circle calculator”. Since I am running three rows of ports, I calculated that the next rows would each be another 12 degrees away, with the center row being offset. This 70 degree included angle provides clearance for the front sight and should prevent fouling. I ended up starting my ports 35 degrees from the top on each side. Any choke tubes and front sight assemblies need to be accounted for, or you can end up cutting through a changeable choke system or heavily fouling your front sight assembly with carbon. Since the barrel is basically a giant lever, moving the ports closer to the ends will help it work better.

Consult a professional if you have an doubts about the hole size and pattern you plan on trying with your gun. Use caution planning your own porting job to make sure you do not weaken the barrel.

I ordered the following items from Brownells: In this post I will be porting a Remington 870 Police 18.5″ barrel. When available, using a milling machine and an indexing set up (in this case a horizontal rotary table with chuck) allows a far greater range of porting sizes and configurations. This method worked well, however, you are limited to the pattern and drill sizes established by the fixture. Previously, I showed how a shotgun barrel can be ported with a simple fixture and a hand drill, see: Porting a shotgun barrel with a drill.
Porting a shotgun barrel can help reduce felt recoil and muzzle rise for the shooter.
