Typically the difference between go and no go is .006. Custom makers chamber to about .001 over the go gage. For them this is easy....they take an hour to do it right.

In a production environment it's done in seconds.

Some I've seen actually bore the chamber with a CNC having used a carbide roughing reamer first. It too is fast and superbly accurate.

Today's cnc machines are capable of controlling a few "tenths"...meaning .0001 inches or a few of them.

IMO there's absolutely no reason why any more than a extremely small trace of out of tolerance head spaced rifles should ever make the public.

as an aside, the local gun shop had a box of Remington made
.17 HMR ammo...they was not for sale because you could see thru the unopened plastic box that one of the cartridges had no bullet in it.

I've been a manufacturing engineer and an engineering manager since 1978. In that time I've also managed QA departments and from my take on this whole thing it seems something is seriously sick in the Remington upper management. These things can be avoided and no one is insisting that they do so. The more I read about Remington, the more I shake my head and walk away. This is not the fault of the workers or manufacturing people....it's directly at the feet of upper management.....if Wal-Mart sales is the prime goal then so be it.......I can buy else where.
