I will keep this short. I made a catch cup to use when weighing charges from a powder measure. I cut the top off of a prescription pill bottle to make a simple straight sided cylindrical cup, that weighed a little under 100 grains, close enough that with some adding and removing of small amounts of Scotch tape, eventually I got it to weigh exactly 100.00 grains. This comes in handy because I do not have to remember what the negative number should be when the scale is zeroed with it in place and then removed. Everything I weigh should be 100 grains high, and when I put the empty container back on the scale it should go back to 100. I know that this sounds a little stupid, but I suggest you try it, particularly if your scale is not perfect, but not bad enough to throw away.
