fffg I assume you already have the mold. Take a 9mm case (fired and with SPENT primer still in place)and shorten it so it holds about 50-75 grains of molten lead. Form a handle from stiff wire around the bottom of the case. You will need 2 pots of bullet alloy,1 hard and the other soft. Get the mold hot and the alloy hot.Fill the nose with the soft alloy,using the9mm dipper ,then immediately fill the mold with the hard alloy.It is easier done than said. Try not to slant the mold while filling or you might get a bullet heavier on one side. Lyman made 2 part molds some time ago ,but they were 357,44 &45 pistol bullets.
I don't think these are really necessary for hunting as a straight wheel weight bullet is about 15 on the brinnel hardness scale.Almost a perfect compromise. They can be shot to 2000 fps with great accuracy.
You can do this in reverse if you need a bullet to "slug up"to fill the bore, but still have a hard nose. jh
