I'm cheaper than ThomasT. I cleaned my P35-22 today, first cleaning since when I got it new about a month ago. I've put a couple tins of H&N Baracuda Match through it and my accuracy seemed to have fallen off a little bit. I'm probably blaming the barrel for my lack of concentration but I cleaned it. I pull a patch lightly wetted with ballistol and then turn it over and pull it through again. Doing it this way I only used 4 patches. I left the ballistol in the barrel and will check it's point of impact and accuracy next time I shoot it - probably tomorrow or Thursday. I also decreased the sear engagement a little and plan to use a new off brand bipod. So we will see if any of these changes improves anything.
The nice thing about cleaning with a plastic pull cord, Ballistol, and cotton patches is you pretty much cannot hurt the barrel.
