Berger make excellent long range hunting bullets. Depending on your application of course. My experience is not with the 28 nosler, but with the venerable .300win mag.
I have taken moose ,elk , whitetail, black bear & grizzly with the Berger's all 1 shot kill's. I'm sure this will get a few hairs crossed, but my last kill was a beautiful 5x6 bull elk @ over 700 yards with a 8km/hr cross wind. Shot placement was no less than perfect & the Berger preformed flawlessly. The 28 nosler loaded up with 180gr Berger(BC of 0.659) & high velocity of that cartridge. I believe the math speaks for its self...
