Not sure I would trust them to expand.
Hornady ELDM bullets are the cat's meow though.
For deer? I've been looking for a bit heavier bullet like the 75-77gr for my valkyrie, seems everything heavier is match grade and I don't know much about them. I always thought they were for target shooting.
Quite a few "match" bullets work very well on deer and other big game, despite being designed "for" target shooting.
Of course, quite a few bullets designed "for" deer and other big game haven't worked very well for their intended purpose....
