I would appreciate suggestions on how to smooth and maybe polish the chamber walls. I think that will help me with sticking fired shells in an Ithaca 12g. pump gun.
So many guns, so little time!

Whoa whoa.
Start by spinning 0000 steel wool, that usually does it just fine.

If the chambers are rough, 4/0 steel wool will do nothing. Nothing. Send the barrel to a good smith and let him hone and polish it. Won't cost much.

I'm a big fan of 'let's identify the problem' first.
4/0 is about 400 grit, if that does not take care of it, there are coarser grades.
Or, you can buy a correct size chamber hone from Flex-Hone for about $40 and do as many as you want. The finish hone is about 400 grit.

I like the stainless pad from Frontier. It will not remove heavy pitting but the surface will look burnished.

JR If the chamber is truly rough there will be highs & lows. The object is to take the highs down. A flat hone stone will do this. The steel wool will polish the highs & lows. There is more to it than just hopping in with a coarse stone @ high speed. John is probably right. Take it to a smith. O.M

Question?
Have you tried Win AA or Rem Premiers in the gun?
They eject fine?
Now are the discount steel based hulls sticking?
Ithaca says they have a factory fix for M37 with extraction issues.

The 870 Express amigos are chamber honing experts. They say Winchester promo loads in 100 packs from Walmart are the worst offenders. I never used those shells so I don't know. I will say this I have not been able to find modern shell sold in USA where the base does not attract standard magnet. I heard Federal Gold Metal paper and Remington STS target loads use brass base, but I don't have any to test with my magnet.

Thank you all for suggestions. The wisest path would be AA or STS shells but I think a brake hone to just remove the machine marks should do the trick also. I was shooting Herter's low recoil shells. I am sure they are steel bases.
Taking it to a smith means a 2 hour round trip to drop it off and another 2 hours to pick it up. It is worth spending some time on it myself first to eliminate the trips hopefully.
So many guns, so little time!
