The stuff is tipped, so you should get some expansion. The question is... is it needed for whitetail? No. Will it work? Definitively, yes.

I haven't shot whitetails with that round, but I did shoot a Scimitar horned oryx bull with it, and terminal performance was admirable.

I will say this about the Federal Trophy Copper loads. The stuff has proven to be exceptionally accurate in just about every rifle I've tested them in to date.

If you're fixin' to put a hole in something,
make it a hole to remember.
