Hi all, I "bit the bullet" (bad pun) and stripped my 336 down and cleaned everything. I followed a great video on youtube Marlin Lever-Action Disassembly and Tuning - Part 1 of 2 - YouTube and disassembled it. I cleaned it all by giving a light smear of oil and deburred edges on the base plate. I'll cycle dummy rounds through it over the next few days but initial tests look promising. The first picture is the 336 in bits with my mud-map so I could put it back together. The second shows the burred edges prior to sanding.
