I have a shotgun in which the chambers have shallow tool marks in them. This does not seem to cause any problems with function as shells go in and out of the gun easily. I would like to have the chambers polished as it is aesthetically displeasing. When I measure the chamber diameter they seem to be well within SAAMI specifications - even a little on the tight side. I've looked at the Brownell's chamber polishing flex hone and it seems like it's not too tough a job.

Any pitfalls if I try and do this myself?
Thanks,
Jeff
