But seriously, I've shot and witnessed hundreds of animals being shot with bergers from a 130 vld out of a 6.5 saum at 30 yards to 215's at 1000ish yards and everything in between.
I've only witnessed one exception to excellent performance. That was a 2020 WY antelope doe with a 156 out of my 6.5 PRC.
Hit her the first time at 592 and she ran off then stopped, thinking I missed, I shot again and no reaction from her.
Then she laid down and I shot her again, this time she flinched but head was still up so I hit her again.
Four shots total thinking maybe two hits…I get up there and start quartering and I find 4 entrance holes. Upon further inspection it seems the first two went straight through her without opening, much like a field point.
I started thinking maybe I forgot to check those tips (which I always do with a dental pick).
When I got home I took out the remainder of the rounds and about 1/3 of the tips were clogged including the next two I would have shot at animals.
I don't consider this a berger failure because I know better and I failed to check the tips.
Since then I've killed a few more animals with the 156 at 2915 muzzle velocity out of my 6.5 PRC including a bull elk at 885 last fall that died quickly after one shot which completely destroyed the heart and lungs.
So, if you are uncomfortable using them…don't. If you do use them please check the hollow point and kill effectively.
