Chambering: indicate bore before threading and/or before reamer?

[Mram10]

I have read of a few guys that indicate, thread and then indicate again before running in the reamer. I have always indicated once in a 4 jaw then threaded and ran the reamer. Has anyone had a barrel move on them between those steps?

Yes, the barrel can move.

Best to indicate, ream, then thread. Its not important that the threads be dead nuts on, but it is important that the chamber be dead nuts true with the bore.

Indicate several times for an accurate chambering.

Whats so Funny???

I’m curious too. I’ve heard of guys indicating multiple times, but can’t imagine the barrel moving once toques down in the 4 jaw. I use aluminum wire between the jaws and barrel.

If you don't have confidence in your setup you need a different setup.

I rough indicate the barrel, rough out the threads to within about .010 inch. I then indicate the barrel and establish the best chamber I can. Then I finish the tenon, set the headspace, cone, etc.

I then go back and check things.

I have never had a barrel move after dialing in. Every chamber gets checked and the Interapid will let me know how it turned out. If it moves, there is a problem. It's all in the setup and the guy cranking the handles...

Has nothing to do with confidence. There is always a better way to do something. Just seeing what other guys do

Thank you, Sir. I’ve read a lot of threads about your setups and they obviously work.

Dave, I guess old M rap showed you. I guess when you have chambered as many barrels as he has you will understand.

You are the worst trash talker, man. Come on, you can do better than that! I’m disappointed in you, yet again

Thanks Dave, but I’m just a normal guy who puts on his pants one leg at a time like you
