A few months ago, my girlfriend bought a XDS .45 acp. It's a very nice, easy to pack little gun and cycles fine with factory JHP ammo. It will not even chamber the cast lead, round nosed ammo I've loaded for my model 625 revolver I haven't gotten to work with it much because 'she' wanted to shoot 'her gun' that day.... But I suspected the wax on the bullets or residual (now sticky) lubricant on the brass. My questions are: Do .45 acp pistols normally cycle cast lead ammo? Should this work as is or should I tumble the cast lead ammo after loading for it to work in a pistol?
