Are you using the S&B Czech surplus ammo? It has a really thick layer of lacquer on it and casings have been regularly sticking in the chamber of both my toks. Clean your chamber really well before shooting and try a pack of brass cased ammo to make sure the problem is ammo related.
lacquer build up could be my issue..the first 40 rounds was ok, but after that rounds started sticking in the chamber.
What's the best method for removing lacquer from the chamber?
