I was saying in another post that my fingers were getting extremely dirty when shooting these pellets in my Condor SS. Also my barrel was getting extremely dirty and when cleaning it, it is almost impossible to pull a clean patch through, even after using many of them. So I decided to clean them and lube them like i do for my .177 Crosman Premiere brown box pellets for my springer. I can't believe how many small filings were left behind after washing the .25 JSB pellets. And after lubing them and drying them they looked nice and clean and handling them a little wasn't a filthy mess. Im not saying anything bad about the pellets....they are awesome and i use them almost exclusively now. But I wonder if this will help with accuracy and barrel cleanliness?
