.30 Carb Blackhawk chambers

Anyone who has one of these knows that case extraction/ejection can be a bit of a problem. The tapered case and the high pressure of the round often add up to sticky extraction.

Is there a safe home brew method for doing a monumentally light buffing of the chambers, a minuscule amount at a time to polish them just enough to see even the slightest bit of difference without wrecking the cylinder of my Blackhawk?

Tools, compounds, methods? And for the inevitable "take it to a gunsmith", anyone know what I might expect to pay for such a task?

Thank you.

I've read that shooting a few boxes of Wolf steel-cased ammo helps. It's worth a try, but I can't find it locally anymore.

Sir
In the past years I've found lots of Ruger (particularly single actions) that had machining marks in the cylinders.
Yea, I've used a split dowell with very fine emery paper to smooth up the cylinders. Not very much but just enough not to change dimensions but just to smooth things up - and it worked really well. I stayed away from the chamber mouths and left them alone but I don't feel it hurts to polish the chamber area. I used my drill press.

+1 on the bore hones. Then follow up with a bore cleaning mop with polishing compound and a drill press.

If you dont have a drill press, then use a hand drill at slower speeds and be carefull to keep things straight.

I have had to do this with a few of my revolvers and it works well.
