Like Ian said, play with alloy and heat treating. And yes, keep stuff labeled really well. I have a bunch of little zip.oc bags of bullets with notes written on them. This like alloy, heat trat, and the date quenched. Keeps me from having bins of bullets where I don't remember what is what. Yes, I have done that too. It doesn't work out so well.
