Re: Cleaning so not to remove moly
When I used moly (once, for the 2002 Spirit of America weeklong Match, the ammo was made for all of us by a Teammate), I would clean daily, after I'm guessing around 50-100rd, with a very cursory wet patching with Hoppe's #9 followed by a few dry patches, then finish up with a patch soaked with a moly bore prep solution. Accuracy remained impeccable. There was no reason, IMHO, to clean very deeply, or to disparage moly in any manner. Very simply, it worked.
Afterward, I reverted to my non-coated bullet regimen, and after several shootings sessions and pretty normal non-moly cleaning method sessions, the bore appeared to return to normal (whatever that is), according to visual inspection with a Hawkeye borescope.
When using moly, I think the above advice about waiting for a good reason to clean makes perfect sense, and unless I've got some sort of compelling, information based (as in borescope-visible evidence) reason, getting overly aggressive about that cleaning doesn't.
Moly's not my thing, but accuracy and cleaning have nothing to do with my reasons.
