Looking for a starting load for a 325 wsm. A friend of mine had one made and is looking at getting into reloading. He wants to use my equipment before he makes the dive and buy his own. I dont have any data on this cartridge and I emailed hodgden which makes the ww780 supreme he got to start loading this cartridge. He has 180 gr bullets and magnum primers. Ive got some 4831 we might use if I cant find data. Im open to suggestions.
