A Lyman 457-193 is hard to beat. It will drop out at about 405 gr or the 457-643 if you can find the old Ideal mould. That bullet drops out at about 400 to .410 gr but it is a fine bullet for shooting "dirty" carries plenty lube and will work fine in the 2.4 case seated deep for fast load and shoot used for a hunting situation with black powder.
