I shoot Nosler Partitions and have shot them for several decades... they are a great bullet... problem is you relly do not get a chance to recover to many...
The 50 cal Noslers are designed to espand to .75/.80" - down to the partition and then continue to penetrate. They are designed to open in fleah as well as bone. It is a well know fact that they have a greater expansion range than most any other bullet. Not ony do they well and penetrate they do cause a tremendous amount of 'hydrostatic' or hydraulic' pressure that causes the delicate vital organs to explode and change to 'jello'
Here is a picture of a .458 Nosler recovered from an elk. i estimated (I am terrible at it) but I estimated close to 200 yards - it lasered right @ 180.
This is a .452/260 grain Nosler recovered from a stump behind where I shot a whitetail...
If you look at both bullets you can see the long bullet shank loaded with lead that keeps the bullet driving until expends all of it's energy or exits the animal.... and most of the it will.
