Okay I'm coming to some of the pros here on the forum for an answer that I can't figure out using the reloading books I have on hand. My son was gifted some old components, one of which are a couple of boxes that are marked 38. What would these be used for? 38 special? 38 super? 380 auto maybe? The dia. listed on the box and the weight of the bullets doesn't line up with what I find in my books. Any help anyone with more experience than I have will be grateful and very much appreciated.
