This is a simple spreadsheet I worked out, designed to take the hassle out of alloy melt calculations.

When you've downloaded the file:
1. The first box is for working out how much lead and antimony or tin is in a given weight at a given ratio. Change the red figures to the weight and metal percentages of your ingot or alloy sticks.
2. The second box works out how much of each metal go in a given amount of melt. Change the red figures to the weight and percentages again and the results show you how much of each metal you need by weight.
If basing the second box figures on the results of the first box (ie. due to use of ready alloyed lead/antimony or solder sticks), then it's up to you to deduct the totals in box 1 from the totals in box 2.
Hope this is useful to any bullet casters out there.
