Please tell if this is or isn't a possibility:
Cast pure lead straight into de-rimmed, sized 22lr brass and fill it up as if it were a cup, then mash it upwards into a tip swaging die. Seems if you had the depth right, it should take the form you wanted, or if you had too much lead in the cup and a leak hole, extra lead would get vented out...? You'd only need one uberexpensive mashing die and one modified affordable Lee 224 sizing die...?
I saw someone that had a youtube video about placing the cups right into a specialty mold for making 223 projectiles that got me thinking about this...
Thanks!
