What you have is Leverevolution brass. It's about .070" shorter than standard brass. I unknowingly picked up some at a gunshow. I was priced at $20.00 for 50 pieces of primed, and I jumped on what I thought was a good deal.
I ws able to load it with my RCBS dies, but since it was so short I couldn't crimp it, so I bought a Lee Factory Crimp die. I then had to grind off .100" in order to get it to work and I'm still not convinced it's crimping correctly, but since I shoot a single shot it's not that big of a deal.
If you have the Hornady dies you'll be fine using the brass but bear in mind the decreased case volume when working up loads. I shoot Trapdoor loads in my Handi so it's not much of a concern for me, but if you're shooting full power stuff you might have an over pressure situation.
I load mine with 405 gr cast bullets but OAL isn't that big of a deal in a Handi. A levergun might not feed properly with the lessened OAL, I really don't know.
I'll continue to use mine until it needs to be replaced, but I'll never buy it again. Too much of a hassle.
