Twist in my copy is 1:8.
There are a couple of places on ammoseek.com that have it. I haven't ordered it in a couple of years, but I do remember it disappeared for awhile. As I recall, I contacted Hornady and asked. The response was, they run a big lot of it and distribute it to vendors, and vendors had pretty much run out of it. They gave me a date for when the next lot would hit the street... and it did.
