They were developed and marketed specifically for longer range shooting where the velocity had fallen off.
Back in the Jurassic era the standard issue Core-lokt bullets would not expand at longer ranges where the velocity had fallen off past a certain point. Remington addressed this with the bronze point which would open up even at lower velocity. All of their advertisements showed some smiling sheep or mule deer hunter in the mountains and open terrain.
Of course, just like the first Ballistic Tips, people fired them at 3000+ fps MV at targets 50 yards away and complained when they opened too fast.
This is all from memory, btw, I never used them, just remember the ads and the stories. Also FWIW, I just bought close to 200 150 grain 30 caliber BP's from the Classified's here. We'll see how they shoot in a couple of .308's and a trio of '06's.
