Berger bullets are for paper only, BUT, because of John Burns, and his feedback, Berger has become his sponsor, and yes, they are similar to Sierra Matchkings. Strong enough for an animal, but made for paper.
I spoke with Eric at Berger just the other day regarding this very subject. He is the one that told me about Berger's shift to long range hunting.
My only question to him was, what if I'm out searching for that 625 yard antelope and I see him at 50. If I shoot, what will the bullet do? I've not heard back as of yet.
