Board policy mandates I state that I shoot for BCM. I have also done work for 200 or so manufacturers within the firearm community. I am prior service, a full time LEO, firearm instructor, armorer, TL, martial arts instructor, and all around good guy.
I also shoot and write for various publications. Let me know if you know cool secrets or have toys worthy of an article...

Quite simple. There are companies that make hammer forged barrels and put the specified port size in the barrel. There are other companies that have the finished barrel and they port it in house to ensure consistency. They also hand polish the feedramps and polish the chamber.

Especially considering how they are still chrome lined at the end of the day, and that's what is making contact with the bullet/powder/jacketing, not the hammer forged steel itself. I'm not seeing how it would be possible, and haven't seen a difference in my BFH and non-BFH barrels.
