In my experience Sciroccos expand and penetrate more than InterBonds (which expand VERY widely) but not as deeply as AccuBonds--which penetrate almost as deeply as Partitions. The Scirocco jacket is heavier, but made of pure copper, which is a little softer than the gilding metal jackets on the AB and IB--which is a mild brass (copper with a little zinc) used for most centerfire bullet jackets.
Sounds like in the end, they all work very well. Just splitting hairs, which ever one is the most accurate is the one to go with.
