Something I've noticed with a pet rifle (stainless 77 in 357) is that when I clean with CLP and only CLP it makes for a lot easier clean up if I get any leading. If I find I have a lot of powder fowling and use #9 it seems to cause more leading if I don't go through and reclean with CLP. This does not seem the case with carbon steel barrels, only with stainless.
I know CLP has teflon in it so is there something going on at the microscopic level with the stainless that is allowing it to get a "non stick" condition ? blued barrels just do not seem to care either way though I hardly shoot much cast through anything these days other than the 77/357 rifle wise.
