Berger bullets are fragmenting bullets on impact by design.
I had long used Nosler and Hornady bullets (I still do, though) before transitioning to Berger bullets as my go-to bullets in 2003. One of the things I like about Berger bullets is that they do not have to have an exit wound to be effective. I no longer worry about pass-throughs or bullet weight retention. Also, it reduces the risk of shooting what is behind the target.
I am not here to convince you that Berger bullets are magic bullets because there is no such thing despite any claims, and you should use them. Pick the bullet that is best suited for your hunting needs. As with anything else, we all have different personal preferences and experiences. I am a sucker for trying different types of bullets from various manufacturers, but Berger has served me well for a couple of decades now and still going strong.
Be advised that you will receive varying opinions, some off-topic, hijacking your thread.
Good luck, and have a happy and safe hunt.
