.32 balls are pretty hard to find. My daughter has a CVA .32 squirrel rifle that I built from a kit years ago, and until recently, it was seldom fired, because we couldn't find balls, and never made the effort to find a mold. I finally got a Lee mold for it (.310") a little while ago, so we are good to go. My advice would be to get on the mold thing right away, or you will be frustrated, and not able to shoot it. I got mine from Wholesale Sports, they are a Lee dealer. Cost like $35. While you're at it, start tracking down some black powder and percussion caps. Oh, and some pure lead to cast the balls with. And if you don't pour your own, start looking for a friend that casts bullets... Don't worry, it will be worth it!
