"You can burn it out with a few black powder rounds.   But firing jacketed rounds will usually iron in the lead deposits in guns that are firing pistol-caliber cartridges.\n \n\n\n\t \n \n\n\n\tYou really need to fix the root problem (leading) with bullets that:\n \n\n\n\t* are soft (no more than 9 Brinnell hardness) (which is just about wheelweight hardness)\n \n\n\n\t* fit the groove diameter of the barrel (and a great fit is one thousandths of an inch  over groove diameter.)\n \n\n\n\t* contain soft lube which actually works as a friction fighter\n \n\n\n\t* and DO NOT have  a bevel base.\n \n\n\n\t \n \n\n\n\tAnd, in revolvers, the throat in the cylinder shouldn't be tighter than the groove diameter of the barrel, and each throat should be consistent with the rest.\n \n\n\n\t \n \n\n\n\tThe modern \"cheap and easy\" approach is to use poly coated bullets, but even those need to be a good fit to groove diameter.\n \n\n\n\t \n \n\n\n\tLoad right, and you won't get leading that then has to be cleaned out.  I've not had to scrape out lead deposits in cowboy guns for the last 7-8 years now.\n \n\n\n\t \n \n\n\n\tgood luck, GJ\n \n\n\n\t \n \n\n\n\t \n \n"
