Question TC barrel stub 17VHA

I have a question, for a 17vha build,

Who can machine a T/C barrel stub of the simplest kind, just a 0.685 bored hole on an old 22lr pistol barrel? Precision bored no threading, just a cylindrical bore?

How deep (long) do you need the bored part? Larry

Likely too deep to bore, would probably need to be drilled and reamed to size. Larry

Kind of a long boring bar and not a large hole, then you have the problem of the interrupted cut at the ejector notch. If you need a truly precision hole through it you would likely be better off drilling and reaming it. Larry

+1 to what Larry's direction. I had a H&R 22 Hornet reamed to 221 Fireball and that ejector notch caused issues with the reamer. Thought it was simple, it was not. I would have asked to have it precision bored, then reamed, had I known.

Question

Thank you gentlemen. Would it be okay then to drill past the notch depth with a tapered reamer to the insert diameter, then ream the rest of the way, or would this entire excercise be easier if I just bought the ready made stub that will still need finishing?

Would a helical ground reamer help get past the extractor cut?
