I would say it has been about the same as what I used to see with 180gr Nosler Accubonds from my 300 WSM or 150 Federal Fusions from my 270 WSM and less than a 7mm 140 Nolser Ballistic Tip from my 7mm STW on the Coues deer. There is always some meat loss around the bullet wound even with monos like Hammers or Barnes. Of course, the monos typically have less than lead core bullets. I try to put the entrance wound low just behind the front leg, so the ribs take the brunt of the hit so not much loss there. It was about same on the African game I've shot with it. I'm sure if you hit an animal right in the meaty middle of the shoulder that entry side shoulder would be mostly lost from any soft lead core bullet.
Here is what I can say about my experience with Bergers, mostly the VLD hunting version. I have used these bullets and seen them used from the following cartridges on Western game and African antelope 7mm STW, 300 WSM, 270 WSM, 7mm LRM, and 6.5 PRC by my father, son, wife, daughter and son in law. None of the targeted animals have been lost, in fact most of them either dropped or took a few steps, but mostly dropped. That's my experience, not everyone's. I have used other bullets, mostly Nosler Accubonds and Ballistic Tips over the years. I have lost 2 Coues bucks to Nosler Accubonds and almost lost a cow elk.
