The Sciroccos have always been bonded. I think Mr. Hober will clear that up. But, like Nosler and the Btip, the Scirocco went through changes with R&D. The Scirocco II looks the same, but they will not dislcose what is different about it v. its predecessor. What they would disclose is simply that there were changes in the process of fabricating the bullet. It is still bonded, same BC, same flight characteristics.
My opinion is that despite that it was bonded, the early Sciroccos had a tendency to open so violently that they looked like pancakes, with excellent frontal diameter, but perhaps a significant loss of penetration.
