I have one in 40/65 that has been rechambered to 40/82. The job looked a little rough so I decided to make a hone and polish the chamber, then tear it down and clean it all, then put back together. Well I went by instructions on Youtube, wrong! I pulled both pins out and like to never got it apart, what a mess. If anyone has some diagrams, or knows a good Youtube video that shows it, please reply, I need help.I can send it to Lee Shaver as a last resort, but I hate to do so.
