Cheers guys for all your suggestions
As per my thread title, the gun is scruffy. The cylinder is devoid of any bluing, just tried cold bluing it, but it doesn't want to know. Just been messing will fill pressures and unusually it likes a low fill ie 170, much lower than BSA, s stated recommended fill pressure. Getting 40 good shots in the high 10,s with JSB Exact jumbos. To be honest I may just wipe with the cylinder over with an oily rag and just shoot the bloody thing, no point in being precious with this little darling
