been there done that. started casting one afternoon about halfway through I stopped for a little break drying the sweat from my glasses I managed to leave them somewhere so I just put on safety glasses instead, after finishing up I soon discovered why I had glasses, one of the alignment pins had dropped completely out of the mould!!! Rats now I'll have to dig thru that pail of bullets to find it, that's when I realized I had cast 3hrs of good bullets and about 4hrs of off-set bullets no doubt for an asperly aimless with an overbore offset. Oh the demons of age have struck again the good side was that there is no such thing as a bad casting experience.
