I've picked up some beater shotguns at auctions over the years, and some of them could really use a barrel hone -- a few heavy, a few light.
I watched a video of Larry Potterfield demonstrating a Sunnen hone system that looked great, and I've seen the lighter Flex-Hone brushes as well.
Any experience or advice with either of these styles? The Sunnen video was on the older side, so I wasn't sure what the modern take on it was. I'm open to anything and cost isn't *that* much of an issue. First and foremost, I want what's going to work well.
Also, long-time lurker, first-time poster. I really appreciate the outstanding content and discussions this forum has provided all of us!
