I just picked up my M-28 today. It shoots great, but you have to rap on the extractor rod with something to get the empties out. I gave the chambers a thorough scrubbing, but it is still tight.
I think there may be a little light rust in the the chambers. The gun wasn't shot much, so it is possible that it may have accumulated a little corrosion.
I thought it might be bad ammo, but the cases aren't bulged and they are within spec for length. The ammo was 158gr Federal JSP.
Is it OK to do a little gentle polishing with a peice of emery cloth or fine sand paper?

I would try Flitz on a tight patch & jag, or a little JB bore paste before I tried 600 grit wet/dry. I think Brownell's sells a little kit for polishing out chambers. Go slow!

The chambers in "N" frame .357 Magnum revolvers went through a special burnishing operation and should be especially smooth. However if you have a problem Brownells (http://www.brownells.com) have special chamber hones that are designed for this purpose. That, and an electric drill, drill press or lathe will fix things up. Be sure to also buy the special honing oil that should be used with the hone.

I don't doubt that they were smooth at one time, but I think that lying in a safe or gun cabinet, possibly loaded for years, may have led to the sticking. I did a little with some emery cloth tonight right after I posted. I just wrapped a small peice aroung a pencil and lightly twisted in the chambers a few times.
Before I had to literally force an empty casing in, and it was even more fun to get six out. Now they just fall in, and come out with only a touch on the ejector rod. I think I have it fixed, but I will need to put some rounds through it to see. If not, I know a smith who deserves my business. He has been around for more than thirty years, so I think he could handle it. I don't want to subject that work of are to too much of my redneck basement gunsmithing.

I use a dremel and semichrome.


Works really well.
