Unless maker’s changed something, they are the same bullet for .458 Socom, just made to .4515 diameter. I haven’t tested the ones I have, but hope to as some point. One thing I’m going to take a guess at, is these will want to be run pretty fast. If you look at Black Butterfly’s website, they show a pic of an expanded bullet with their 100yd group. It’s fully expanded, but just barely (petals are almost straight out). They run them a little over 2000fps IIRC. With this company they are running them about 100fps faster and getting the petals to fold back a bit. So I am going to guess they probably won’t shed petals, unless ran extremely fast and hit something right out of the muzzle.
Also, they little bit I did play with them, they hit pressure before the 275 TSX in my Tromix barrel, so if you reload them, start lower or try a little bit slower powder.
