Subject of my issue is an older Taurus 607 seven shot 357 magnum. It has been very accurate and reliable for years. Issue has been just recently with a couple of light primer strikes that have barely marked the primers. I’m thinking it is likely due to the fact that I haven’t used it in years and things may need to be stripped down and cleaned real well. However, I have ran it real dirty before intentionally to test it and never had an issue. Not sure if something has worn out and needs replacement or what. I have cleaned it up as I have before and still had some light primer strikes. I’m no revolver expert by any means and wondering what I should be looking for and what I should be checking.
