I didn't read everything here as I know more or less how these threads go but I will give you my first-hand experience with Berger bullets. VLD, Classic Hunters and Hybrids.
Now I have hunted quite a bit in my life, im only 34 but I have hunted for the better part of 28years, multiple times every year. I have been on “culls” in Namibia where we took 200 head of big game (Oryx, Koedoe, black and blue wildebeest) in a week. Have shot just about everything Africa has bar the dangerous boys, I have tried everything from Barnes, Custom Monos, Amax, Scirocco, Game Kings, Interlock, Ballistic Tips, Acubonds, Aframe (still shoot them in my 375), partitions you name it im sure I have shot them In 22, 6mm, 6.5mm 308 and 375.
There is no other bullet on this planet that hits with more authority than a 215gr Berger Hybrid out of a big 30. In the last 2 years we have shot close to 100 animals in our hunting group with Hybrids (the 140gr out of a 6.5 is also spectacular) multiple VLDs, 140gr Amax and 147gr ELDs. IF I recall only one animal required a second shot after receiving a Berger, from 80y out to 880y we have 1 shots kills on everything up to and including blue wildebeest with the 215gr Hybrids and we are yet to recover a bullet. As a local tracker once said after watching a animal being shot by n VLD......its like he ran into thors hammer... that got thrown out of a speeding car.
If Berger made a 375 cal bullet I would have that loaded in my 375 as well
