Well I have measured an eclipse barrel at 6 micro inches finish. when I bore a barrel I run a reamer and then a flex hone to get out the tooling marks. 600 grit for about 15 seconds I have measured that finish at around 18 micro inches (if memory serves). I recently decided to start on a project for dansoslow and make him a custom barrel. I tried reaming a tube that was already close and I was not able to get it quite right in the middle. I had to flip the barrel over to reach the whole length. So I am embarking on plan B I went ahead a bought 2 11/16" gun drills 22" long and plan to try making the barrel 100% from solid stock. I will let you know how it goes cause its going to be an adventure.
