I haven't actually used the 25 Hornady. I have a bunch of them, but haven't ever needed to try them.
When you say "25 Berger", things get fuzzy. The 25 Berger that we are talking about was the old, old, old 25 "Match". Berger applied the same name to a different bullet later, then mixed things up again with the "Varmint Match" and so on and so on until the meaning of "25 Berger" has gotten hard to keep straight.
The old 25 Match had a teeny, tiny, super tight meplat. Which was it's secret sauce for "controlled expansion". At MV's in the 3800-4000 fps and ranges under 200 yards it was "just right" for coyote. And had just enough penetration to allow for a direct shoulder hit without pure splash.
Back when Clint Starke was making bullets, I did a lot of prototype testing for him. And I could never talk him into making a 25 (or 30 for that matter) with that tiny meplat. His reason, which made perfect sense, is that you'll occasionally get a punch stuck in that tiny HP and have to stop and replace the punch. And from a one man elbow powered operation, that just didn't make financial sense.
When Clint got out of the bullet business, Chan Nagel bought his dies. And bless Chan's heart! First time I talked to him, before he had even started to sell any, he was onboard with the tiny meplat and while he was operational, we had a really good coyote bullet. And more than that, when J4 stopped making long .17 jackets, he endeavored to make his own jackets which were every bit as good as J4 and he provided a really good 30 gr. too.
But, long winded way of saying, I haven't actually used the Hornady so can't actually answer your question!
