Well, these days I just use the Chore Boy but in years past I was told by some very old old timers that the best way to get the lead out was fill the bore with mercury, let stand for about 5 minutes, then drain the barrel. One tight patch and the lead was gone. Take my word on that, it works without you having to do a lot of work. Of course these days, I suppose possession of mercury is probably illegal.
Also years ago the was a treatment for head lice called Blue Ointment. The main ingredient was supposed to be mercury and was supposed to get the lead out quite nicely but Big brother outlawed that as well.
SAs was said, just use the Chore Boy or a Lewis Lead Remover. One way to alleviate the leading problem is get away from super hard bullets that won't bump up, especially at handgun pressures and use bullets properly sized for your firearm. I've been using bullets as soft as 8BHN but normally prefer 11 to 12 on the BHN scale. I've shot an 8 BHN bullet from a .357 Mag. at full power with no leading and great accuracy. They're sized at .359" for my revolver. In all honesty the bullets also have a gas check but the same bullet at 22 BHN, same sizing and check would lead the barrel badly. Naturally, YMMV.
