hi all. I am casting lee 106 gr swc heads designed for a 38/357. powder coated and sized to 357 for use in a 9mm with 356 bore 4.2 GR BULLSEY.(very accurate) the problem is they smell bad when fired and I have had complaints during steel challenge competition. I cured the paint for over 30 min on one load and it helped some. I would like to try a plain base gas check on the ammo I shoot for the matches. what size would I need and how do I apply them ( I use a lee push through die)
