Well, I took it to the range. It fired a decent group at 15 yds but, with rear sight all the way up it was still low. I replaced the front sight with a much lower one.
But, I also had regular fail to fire. breach I could see space between block and back of barrel. I have no idea how much is to much on these. But, using the lathe I turned .012 of back of shoulder on barrel that goes against the action to close it up as much as possible. I also hit the firing pin repeatedly with brake clear and worked it. Screwed hammer pivot screw out until I could squirt a drop of oil under it and tightened back up hoping head would force it down stud and into hammer. It then fired 5 cases with the bullet pulled from them. Cloudy and over cast. Have another 22 I want to check out next trip.
