You are better off sticking with the original pin. It requires a 7mm reamer to finish. I mill the channel whith a ¼ inch center cutting 4 flute end mill.
The reason I do not like oversized pins is not only does it give you some place to go if you mess it up. It also insures the rifle can be repaired in the future.
You can only go so big until you get to close to the chamber. Mess it up with the large pin and the barrel and trunnion are FUBAR
