The brass used in Barnes banded solids is indeed very soft... I have shoot several of them into oak logs and all of them were deformed at the tip... much more than the bullet in the photo. By comparison TB Sledgehammer made of said "naval bronze" deformed very little or not at all. And this is a bullet with soft lead core not a monolithic.
I dont know is this really as good as they say. For the barrels maybe but you know - you shoot elephants with this bullets and they deform...
