I think we have a couple barrel makers that cruise through here. When your cut rifling a barrel what is the feed rate of the cutter as it passes through the barrel? I believe the depth of cut to be around .0001? Does the feed rate change per caliber or groove width?

Thanks
 
I am guessing the general feed rate isn't that "secret" as compared to cutter head design, material and geometry that they have really worked on. I am guessing it's a very large range though. If you consider people are using everything from the P&W 40's era machines to new fancy CNC everything.
 
I would really just like a real world number from someone that actually does it. If I don't get any answers I might just call a couple of the cut rifle guys and see if they are willing to give me a range. I just hate to interupt them for trivia questions.
