If you just stick your finger in, won't you get a cylinder, rounded at one end, and flat at the other? Flat end cause liquids always find level- think of a glass of water. I watched pewter spoons being made once, and I think the guy used plaster of paris as the mould.
I would suggest the following route: - take a candle and carve a glande, or soften the wax and form one by hand - take a plastic cup, half fill with wet plaster - stick glande halfway in, point down - fill rest of cup, JUST covering glande - when set, remove platic cup by ripping it off/apart - cut down center with a saw, old, coarse hack saw best - remove glande (stick in oven, over fire and melt out) -remove top off of mould until the top is just exposed - use a leather thong, copper wire to hold mould together - fill with lead - allow to cool - remove glande - finish with a rough file
I've used this technique for making a keel weight for a toy sail boat, a rubber beer bottle for throwing at friends (they're bloody shocked when it bounces 15feet!) and other stuff.
