I am looking to cast and load 35 cal. No lube groove boolits for use in sabots. I have a Taurus Judge. You can use 444 Marlin cases to make 410 shot shell loads. So why not use a 410 shot wad to load a .357” to .360” cast boolit of 225g to 250g, SPBT. This combo will be much more ballistically clean then the 45 LC boolits and the long boolit in a full length shot wad do a fair job of filling the 452 bore. Yes you will have a concentricity issue, but deeper penetration and may hold just as tight a grouping. So the question, other than the expense of a custom mold, are none lube molds readily available in non-lube configs by cal & wt?
