Hi Toby. I've been trying the process on my Lancaster sidelock barrels and it's going pretty well...even with my current browning solution as the rust activator. Looking forward the proper stuff. I've got the dreaded bleeding ribs problem, just a tiny little bit near the breech end...I'm on top of it but it is a right royal pain in the arse! I'm at about my 5th cycle now and the barrels are a nice deep grey rather than I would say "black" so I just keep going until I'm happy? Then is there a fixing process you would recommend prior to oiling at the end?
Regards,
Tony
