Greetings everyone!
This is my 2nd post here so be gentle. My knowledge of gun repair is very, very light.
I have an Iver Johnson 22 slide action that I purchased new around 1980ish. I used it a few times plinking with my Dad and it was stored away until now.
The problem is that about 1 in 10 cartridges misfires. I've attached a pic of a fired round that I shot with a working 510 Targetmaster and then chambered that same spent cartridge into the Iver Johnson to make a comparison of the two indentations. I did notice that indentation mark of the Iver was not as deep and didn't bulge the rim like the working 510. The edges of the mark do seem to be sharp.
Thinking that something was slowing or blocking the striker/pin (I don't know what it is called exactly) I stripped the gun down as far as I would dare and cleaned the parts with solvent (Hoppes) and removed any dried grease or debris. I lubricated and reassembled. It took a long time to get it back together because I could not figure out how to get the hammer, slide, and everything to line up. If someone could point me to an article or how-to it would be much appreciated. I took another spent cartridge and did the same indentation test and the results were the same. The indentation seems too weak compared to the 510. On the plus side, the gun is now very clean.
The striker/firing pin does move back and forth in the housing (again not sure what it is called exactly) and hammer moves freely. The sound of the hammer hitting the pin sound a little soft to me but I don't have a reference to compare it to. It's not the solid sharp click I'm used to.
Is the amount the pin moves forward by the hammer adjustable? Should I replace the spring that loads the hammer before I do anything? If so, where do I get one?
Thank you for your help and do please correct my naming of the parts so I can learn a few thing along the way.
Best regards,
DeBug
