The person making the claims should be the one who provides the proof. Think about it.

You claimed i was wrong.
Where is your proof..
Put up or.....

i proved the ONE SOURCE claimed was not a source of precision rifles, but tactical and hunting rifles.

I just added a person in co to my ignore list.

Never had to ignore anyone, regardless of their tenacity, but maybe time to. My guess is the "Covid" thing is working on some different than others and must give them the benefit of the doubt. Let them get the nasty out of their systems.

Anybody that searches "precision" rifles will come up with a list of at least 10 well known manufacturers.
A search of custom rifle builders that do not use reamers with pilots comes back basically empty. I've "ackleyed" a couple of chambers without a pilot but we all know the reamer will follow the original chamber, simple physics. No one should have to prove anything, especially when using subjective terms.

that is how precision rifle chambers are cut.
the bbl is taper bored to match the reamer.
the tapered bore guides the reamer.

Mike, You speak of truth and facts. You stated earlier that you were a national champion. Can you give us some facts. What year did you achieve national champion status? Who was the sanctioning body? Discipline? Number of competitors? Remember, I know.

Too bad all smiths didn't have equipment that "tight". They could dial it in at a fraction of a tenth and then use they could use all their old reamers because the pilots wouldn't even touch! Biggest advantage of using no pilot would be to a more effective flushing during operations. The setup for quality chambering is most important. If the lathe won't hold the tolerance, no amount of setup and prebore is going to make the chamber "true". The benefit of more effective flush is probably the biggest advantage, similar to cutting a chamber by hand with frequent cleanings every .010 or .020.
The end result of a "clean", "round", concentric to bore is attainable in more than one way.
The term "precision" is being used pretty loose and actually would be an insult to a bunch of top end smiths who build rifled for a host of competitors and "national champions".

i was pretty clear with the word precision...as in not hunting and not tactical.
