( Yes , bbl straightening by mfgs is a longstanding , generally accepted thing . This one would seem to be right on the very edge of a very generous Factory Spec .)

I understand barrel straightening is commonplace in production models but some are impossible to thread as they are now warped and non-contrentric. I could just get a replacement 7.62x30 Ruger barrel, but I have no guarantees that I would not have the exact same problem of being able to suppress it without risking a baffle strike.

Hence, my decision to just get a threaded barrel and go whole hog with a better cartridge chambering. Good news for a friend of mine is he gets a few hundred rounds of various 7.62x39.....unless I decide to get a 7.62x39 Ruger American Ranch to use my old Mini-30 magazines in...hrmmmm

A whistle-blower was reporting that he spotted workers bending M16 barrels to install and then send out to the Army. There were numerous industry expert witnesses from different gun companies testify that was not unusual as there was no such thing as a perfectly straight barrel and that's why there were inspection procedures. If a barrel could be brought in within specs it was done...otherwise it was scrapped. Procedure today are probably far better than fifty years ago.

Ruger has an excellent customer service reputation. I doubt if they're screwing with you. As long as the rifle shoots the way you want it's really nothing to worry about.
There is a photo in canfield’s book of a worker bending garand barrels. Oops. Photo Posted in this thread. Sorry. Didint see it.

The problem started when you decided that you want a mini-30 to do something it's not designed for.

John took care of you the way a good gunsmith would by letting you know what he saw. You can't ask for more.

P.S. He built one of my AKs.

Oh, I have absolutely zero complaints about John. I have tossed much work his way and he has always delivered 100%, a couple times he even exceeded 100%. I have more work for him sitting in my safe waiting for me to gather the funds.

My complaint is entirely and completely with Ruger.

They currently offer a Tactical Mini-30 that comes with a pre-threaded barrel. Why could they not sell and install one of those? I doubt highly that the threads are different.

Side bar: why is “bbl” the abbreviation for “barrel?” I can see it being an abbreviation for “bull barrel” (sort of). But since “barrel” is one word and has only one B, I’ve always wondered about that usage. See it pop up here once in a while, so I’m sure that after 40 years or so talking about barrels, I’m missing something. I now return you to your Ruger programming!

This is what I could find. It's not even a firearm-related reason.

bbl = blue barrel

Well THAT's a bad fit! Good to know that I'm not imagining that it's counter-intuitive in this context.
