If there is interested start another thread about break in and cleaning of custom or after market barrels and I’d be happy to discuss it , factory barrels are high production with an emphasis on speed and cost vs what the market will tolerate for quality , and everything we do to “custom “ barrels probably would to little to help , there are exceptions but in the big picture they are rare , apples and oranges,
Rough chambers are bad news , iclund is correct about a good smith and a sharp reamer will produce a good chamber .
How ever we have tested chambers up to a 2500 grit finish (polished ) and had non of the issues claimed ,problem is most people will wreck a chamber polishing if there not careful ,it’s easy to make the chamber big at the back if you get aggressive ,
