I also use Sheath it will put the frist shot in my gun to the point of aim with RS or with APP FF; I scrub till completely clean with hot soapy water wet a patch with Sheath and put a light coat on the boar,when ready to hunt I just load and go as I have tried this out at the range many times; remembering that each gun is an individual I would suggest that you do your own test to check what your gun does.
