My experience with moly coated lead bullets seems to have eliminated leading. I like them and use them when I load cast bullets. I have read that the acp shooters have had problems with deposits at the end of the chamber, resulting in headspace jams. Rimmed cases dont have that problem. Some bullet makers claim you can drive these as fast as a jacketed bullet, I have not tried it. My 357 'plinkers' all chrono between 1210 and 1220 fps, and accurate. The only non-coated bullets I use now are gas-checked heavy weights.
How do they work for you?
