I've never reloaded before, but am about to start within the next year. I was gifted a .375 h&h ackley improved. It came with 5 boxes of .375 h&h 300g partitions, a set of reloading dies for .375 h&h, and ~18 complete rounds and ~25 fireformed .375 h&h Ackley improved cases. Please correct me if I'm wrong, but to reload for this I need the AI die set and not the standard .375 die set, correct? If so, where is a good place to pick up a set? Tradsies?
