"if you load lead bullets and don't get leading you must be magic, and if you load plated bullets and do get leading you must be cursed."
No, you either understand the ins and the outs of lead bullets or you are lucky. The first group of people understand what causes leading and one by one eliminate those causes. The second group of people just buy commerical cast bullets with no regard to anything and shoot them with no problems. Keep in mind that there are tens of thousands of shooters out there shooting lead bullets. There are many thousands of people casting bullets at home. There are plenty of them shooting cast lead bullets in centerfire rifles and have no problems. Obviously, if you are shooting them out of a relatively low velocity pistol and are having problems, you need to re-evaluate what you are doing wrong or just stay away from them. This of course is not to mention that if you are using the right tools, leading is not a significant problem. I am currently working with a .45 Colt Ruger Blackhawk that is leading. But, I have a Lewis Lead Revmover and can remove the lead in less than one minute no matter how bad it is. I can currently evaluating why I am getting leading and will, shortly have the problem solved. I regularly shoot cast lead bullets out of my Super Blackhawk using max loads and get very little leading. I am talking about shooting a couple hundred rounds and having the bore clean with one pass of the Lewis Lead Remover. If I tone down the loads just a little, there is no leading at all. I shoot thousands of .38s and .357 cast loads every year and have no problems at all-zero.
And if you get leading with plated bullets, you are doing something seriously wrong, or have a significant problem because there is no lead exposed. If there is no exposed lead coming in contract with the barrel, it would be mighty hard to get leading. This isn't magic, this is common sense.
