I use the 165 gr IB in my 30.06.
Don't buy a lot of them until you have developed a load - they can be finicky on accuracy.
For whitetails, it is probably wasted money...….over the 165 gr Interlock. But I guess it may give you peace of mind.
I am reserving my IB for moose and elk now and switching to 165 gr Interlocks for deer.
