polishing the throat??

I've heard of micro polishing the throat on a new chamber to aid in breakin. I was wondering how one may do this? I have fine lapping compound but not sure how to apply it. I don't want to ruin a new barrel.

Re: polishing the throat??

This is not a job for an amateur. How do you know it needs to be polished? If the throat is lapped excessively, you can ruin the accuracy. The same thing applies to bolt lugs and using a well known competition shooters "polishing bullets"l. Take it to a gunsmith.
