Sorry @Clubbie for hijacking your thread. Too late now :thumbsup:.
Nothing else for it, it was time to kill some plastic and water and do a little test. So having learnt lots from YouTube, we set up our experiment. We shot a .308 151gr cast lead bullet at 1085fps from 50 yards and wondered what would happen next.

The 151gr cast lead bullet made it into the fifth milk bottle. We were well pleased to retrieve the bullet in a perfectly formed mushroom.

The diameter of the mushroom is 0.566" at its widest, and 0.522" at its narrowest.

Fair to say then that these bullets do what they say on the packet. Would have no hesitation shooting these into the shoulder of close range medium deer and goats.
