I am getting ready to start casting my own bullets. I went and ordered all the stuff I need; furnace, moulds, sizing dies, ect. I will be casting Lee's C309-170-R for my H&R HandiRifle and the CTL312-160-2R for my two 7.7mm type 99 WW2 Japanese service rifles. Both bullets will be cast using wheel weights. I intend to develop hunting loads for all three rifles using cast bullets. What would be the best powder to use for these calibers? I would like to the same powder if possible to cut down on expense. Any loading data for 7.7's and 160-grain cast bullets would also be appreciated. My Lee loading manual doesn't have any loading data for my Lee mould. Go figure.
Thanks.
