You've done the work of casting and sorting. According to the pic, some are sized and lubed. If you remelt, that work is lost. If you trade, then you have to use new resources to make new bullets. That resource becomes lost.
BUT, you asked what I would do. I would load all that fit my guns, and those of my buddies. If what was left had a count of 20 or greater, I would list them in the classifieds or on an auction site. Less than 20 goes in the pot for reclaiming. I have a heavy clear plastic compartmented hobby box made for beads or buttons or such and I use that for my odds of ends of left-over bullets. Keeps them somewhat organized and sometimes I need just a few for whatever and my alloy doesn't change much over time, so my batches usually weigh very similar - not enough that would show in the groups I shoot!
