My 870 express was jamming on low base Winchester shells. I read that the Chamber needed to be polished. I tried my hand at it, and the problem is now remedied, but I have a question for others who have done it.
The guys who I read talking about it said the Chamber should be a mirror finish. Mine shines now, but is nowhere near a mirror shine. It looks more like a brushed finish. I used a brake cylinder hone and finished with a dowel wrapped in 000 steel wool with CLP. Do you guys have any tips on finish polishing this chamber up to make it glossy like a mirror? I'm worried that it being slightly rough will result in fowling causing more jams.
