Yes, of course, they lose their petals all the time!
NPs typically retain the majority of their expanded mass losing but a small portion.
If you can find a NP that has lost/severed virtually all expanded mass at the shoulder junction of the partition, you should share a photo.
NPs just can't compete with monos that have a higher retained weight after turning into what is effectively a FN solid.
mr.Nosler started the ball rolling in regards to [expanding bullet] retained weight and penetration performance for magnum velocities on large heavy built game,...he did a relatively great job but he didn't perfect it.

I recall seeing NPs that tumbled in dangerous game losing the rear core.
something one don't have to worry about with monos.
