OK, my friends. I finally got hold of some .357 Mag brass and I've got a box of 180gr Hornady XTP to load. Don't see any load data for that weight bullet on the Hodgdon site. So far I've loaded 125gr XTP with 8.0gr Win 231 and 140gr XTP with 7.0gr Win 231. Would somebody care to give me an idea on what I should use (Win 231) for the 180gr? Would dearly appreciate it.
