Home moly coated , custom process , no wax . 223 Howa . Clean about ever 300 to 400 odd rounds.
I don't know how much further I could go maybe many more but I stop around that because that's where I stopped during original testing .
I have 400 loaded rounds at a time and when they are gone I clean but if I only fire a few hundred and want to put the gun away I clean then also.
It's not just about accuracy maintenance , it's also about convenience and if you have finished with the gun , travel time home , storage time , corrosion control , etc. It generally takes more shots with Moly to foul the bore again to settle group accuracy so you don't want to solvent clean too often .
Just because I don't scrub with bore solvent as often , does not mean you don't lubricate the bore to protect the steel each day after use or at least when you put it away for a few days or weeks .
Cleaning for accuracy maintenance and corrosion protection is two separate issues .
Uncoated bullets , I clean as accuracy drops off or at convenient intervals that I know from experience with the barrel is about right to keep things kosher .
It varies in each barrel . Usually only takes one or two fouling shots to settle .
