Thanks for all the advice and suggestions. I'll sort out all the spacers and blocks and will smelt all that down and mix it into my other ww alloys for personal use and just leave everything else loose. For my general purpose plinking, I am not particular what the mixtures are. I've found just about anything I PC will shoot just fine in 9, 45, 357, etc. I'll save the mono for things where I need a more known mix.
