Remove the bolt and do a visual inspection of the chamber; also inspect your brass for deformities. Sticky bolt syndrome is not necessarily a rough spot in the chamber; it could be from bad lubricant stuck to the chamber (tends to act up on a hot barrel). Either way, you could start with J-B Bore Bright. It's an ultra-fine grit abrasive cleaning compound used for cleaning barrels. J-B Bore Paste is somewhat more aggressive, which could also be an option. Get a cheap cleaning kit with a 3-piece rod. Put a bore mop (with Bore Bright on it) on one section of rod, and mount the rod into a drill. Run the mop into your chamber and ease the drill up to full speed for about 5 seconds. Clean your chamber and barrel with a liquid solvent like hoppe's. Don't forget to pay attention to the grooves that the bolt lugs go into. Have q-tips handy. If you want, you can clean with gun oil; just wipe it dry afterwards. Proceed to test fire.

You want to 'polish' as little as possible, which is why I said to only run the mop up and down the chamber for 5 seconds before retesting. If bore bright doesn't work, try bore paste. If you have to shoot at a range, bring a cordless drill. I want to say that about a 50 cal mop will give you a good, firm fit, but you'll have to check.
