I have a couple of British side by sides that have been sleeved. Both have problems with fired shells sticking in the chambers. I've tried "polishing" the chambers with abrasive cloth on a dowel and that polishing does seem to help a little bit, but does not totally eliminate the problem. The forcing cones of both guns appear to be very rough but I don't have a bore scope to get a real good look at that area. I see that Flex Hone has both chamber hones and forcing cone hones in several grits. I'm wondering if anyone has experience with the hones and could recommend what grit to use and any special tecnique?

Flex hones are fine for polishing. I would not ever use a flex hone for any real metal clean up or metal removal. If you decide to just do it, the key to getting decent results using a flex hone is low speeds and lots of oil. From what you’ve described, it sounds like a job that would be best served by someone with a sunnen hone. Mike Orlen has a Sunnen, as do many other barrel specialists.

Also, you can get a basic endoscope on Amazon for between 15 and $30, connect to your phone. Make sure it comes with the right angle attachment..

I have used Flex Hones for a lot of barrel cleanup, but not chambers. They can be more aggressive than people think in the large grit sizes. I will say that slow and oil are good but I think the most important thing is to keep them moving fast. A slow drive speed will avoid waves but rapid movement in and out is more important in my mind. I have found that the final polish requires more drive speed in order to get a slick polish.

One thing you might try is to run a bore gauge through the chamber and forcing cone. Personally I would doubt that a forcing cone would lead to sticking shells, even if the chamber is shorter than the cartridge. There may be a bulge in the chamber due to bad alignment of the chamber reamer, but the most likely areas are a tight rim or a tight chamber at the base. Try a few different shell brands, inspect the fit of the rims and the look of the fired hulls. The fit of the ejector/extractor may be the culprit.

I have solved more problems like this with a hand turned chamber reamer than with a hone.
