Before you go drilling, sanding or sending it back may I make a suggestion ? Mind you many posters are much more knowledgeable than me, but, I have bought 4 new 22lr revolvers over the past few years, all different brands and every one has the same problem as yours with ejecting the empties, how did I fix them ? I shot and cleaned them and after 4-6 range trips, 200-300 rounds each trip, the come out much easier, my Uberti single action was the worst it would only shoot 2-3 cylinders before I couldn't push them out. I clean them every trip and now they have no problem coming out. Good Luck, I'm sure it'll be fine.
