I get little , if any leading. I use black coated bullets from precision, and cast I pick up locally, neither lead noticeably. Ive loaded 155 & 180's from 5-6 Grains of Unique, and 4.5-5.0 231. I also shoot cast from our 38's and 357. Thye lead very little, even with fairly hot 357 loads. However, my wife likes those swaged lswchp's from hornandy, and they lead pretty bad, as does almost anything I shoot out of her Judge.
