Indeed. And once I discovered that gadget, life became a lot easier.
But remember that my "drilling days" were as a basic student who was handling revolvers for the first time. Between my dad and the army, I had been weaned on semi-auto pistols. Our instruction at the Academy was little more than "This is a revolver; the bullets come out of this end. There's targets and ammo; go forth and do well." They darn sure said zip about how to clean a revolver; properly or otherwise. So we managed as best we could.
The BEST way to remove stubborn leading is with mercury; which dissolves lead in a blink. Of course, the hazards of that are legion, not to mention the stuff is difficult to obtain (and CONtain). But it sure works…
Anyway, this discussion is why I mainly stick to jacketed bullets for my limited revolver shooting these days. Its just easier all-around.
