Sir Charles, I'm just searching for info at the present time. The boolit I may use will be Missouri Bullet Co. .358 NGC, 158 gr, 18 bhn. My club ( Custer Sportsmens Club ) has a shoot a couple of times a year for long range pistol and lever action rifle. I am not shooting SASS, you guys are too competitive for this ol' country boy. I have 11# of Universal Clays that I use for my 44's and I will substitute it for Unique, I hope. Thanks Jerry
