There's an old machinist's trick - paint up the back of your brass and the face around the firing pin with Sharpie. Wait for it to dry. Then cycle the gun. It'll polish off the parts where it's biding up. Lets you know both where it's hitting your brass and what parts of the gun need cleanup. If only one or two rounds have issues, swap them around and see if different rounds in the same cylinder slot have problems, or it's those specific bullets. Either way you'll get a much better idea of what's going on.
