Has anyone encountered sticky extraction in a 1893? I have a 30-30 and I'm using the lightest book load of 2400 for a 170gr cast boolit. I'm wondering if my chamber is bad or bulged or something hard to detect. I'm going to give it a good cleaning and see if I can't shed some light on it. I've fixed this issue on another rifle by honing the chamber area with a small bottle hone in a battery drill. The barrel had to be removed and I'm not looking forward to doing it on my 93.
