On a whim I picked up two new molds intended (I think) for the .38-55 Win that were going cheap at an estate sale. One is a Saeco/Redding 738 VF3 250 grain and the other a Hoch 376 310 C4899. Are these adaptable for the .375 H&H? If not, what would the experts here recommend as a general purpose .375 mold? Thanks!
