Bullseye in one shot with a Nagant revolver.

[Littlejohn]

Have you tried polishing the chambers?

Yes, I did. Wasn't much of an improvement. I think it's a pressure issue. I have tried jacketed and cast bullets, in the 100 grain range, over 2.8 grains of Bullseye. With the cast bullet loads, the cases extract easily. The jacketed bullet rounds stuck nearly every time. I think that the jacketed bullets, being harder, require more force to get started in the rifling. The pressure builds behind them until they start to move. The higher pressure causes the end of the case to flare to a larger diameter than the chamber. Remember that the cases are longer than the cylinder. The flared case doesn't want to come out of the chamber.

Just my theory on what's causing the hard extraction.
