Not what I said.
It wasn't routinely done to most Mosins during refurb & it wasn't a matter of a "rough bore". It was done to those barrels specifically with worn rifling at the muzzle end, to salvage an otherwise usable barrel, by addressing those specifically with worn rifling at the muzzle.
The practice removed uneven rifling that would cause accuracy issues for the first inch or two, and trued up the last section of the bore.
It was not standard practice on otherwise "good" barrels.
Not even on rough barrels.
I have a sample with what most would call a rough bore, it has full rifling to the muzzle.
It's also outshot every other Mosin I own.
Overall rough bore condition had nothing to do with it.
The vast majority of Mosins were not, either originally or later during refurb, counterbored.
I've gone through several Mosins over the years & never encountered one.
I didn't say or imply anything to suggest that a counterbored barrel had, or still has, a rough bore.
