On the subject of the Fusions, and by extension, the Deep Curl. And I apologise if its above in the thread, but haven't the time to re-read it all I am sorry.

Some of the literature around talks about them being bonded, with the jacket molecularly bonded to the core or similar.

I have to ask, are they a bonded bullet in the sense of the more common variety, and can they be expected to perform the same way?

I don't have much need for bonded bullets at the price they charge, but the Deep Curl is cup and core pricing. I would certainly give them a try.
