I used Berger Classic Hunters with good success out of my 300WM with IMR4831 on Elk, Bear, Antelope and deer home here in MT.
My Barrett Fieldcraft in 6.5CM loved the Federal Factory Berger Hybrid Hunter in 135gr so I did a custom turret on the Leupold etc.
I went to a friends lease in GA and my first buck I shot was at 15yds… the bullet exploded, not a single drip of blood, found the deer 250yds away (dead) and it looked like it was not even shot. Second deer at 40 yards was a similar situation.
I went home and worked up a 127gr Barnes load…
Berger's are made to break up so I guess you could say the bullet did its job. I definitely think bergers are better for longer range (great BC's) performance hunting.
I stick with Nosler, swift and Barnes for hunting (I do want to try Hammers, so many good reviews) and keep the Berger's for F-class and target work.
Meat eater actually did a pretty good test video at various ranges. I believe it's called copper vs lead.
