So I got my boy a Ruger .22 and the gun ran perfect after changing the guide rod. Shot maybe 2K rounds flawlessly. Then go out yesterday and gun shot great but would not eject live round after finishing shooting stage. After each trip to range I do a cursory cleaning. But after issues yesterday did more thorough cleaning and found chamber to be tight when round chambered. So cleaned and removed several large chunks of lead. I am talkin pieces 1/2 mm in size?!? Where does something this big hide? When inspecting gun at range everything looked good. No big chunks of stuff noted. Now rounds cycle great and will test fire soon. But I was just curious if this is normal to have such big chunks of lead in a barrel or do I need to contact Ruger?
