I have read about this in the past and the people who were using it were trying to "clean-up" the lead in an old shot-out barrel so that they could shoot oversize cast bullets accurately.

I think you might find that by shooting some regular copper-jacket ammo thru your old barrel and leaving it there instead of trying to clean it out would leave you with a smoother more accurate bore.

Essentially you are using the copper fouling to fill the deep pits and by leaving this fouling in the bore you end up with a much smoother and potentially more accurate bore. After you shoot your pistol, clean the chamber area ONLY with a 10mm brush, leaving the bore UNTOUCHED. Wipe off the muzzle and push a lightly oiled patch thru the bore. You should see an almost immediate improvement in accuracy.........................
