Just in follow up, I bought 500 of the Missouri bullets hi tech coated 240 keith style LSWC's and have fired them from a 4 inch M29 with 9.0, 9.7 and 10 grains of Unique using CCI primers and various types of brass. I am glad I bought the coated bullets, they shoot well, keep the lead off your fingers, and I cannot detect any smoke...
