From what I understand, the original Berger target bullet was being used by hunters, and they were reporting fantastic results. The bullet had a thinner jacket. The thinner jacketed bullet when shot by target shooters, who generally shoot bullets at higher velocities, would sometimes come apart in flight.
Berger thickened the jacket up to improved their target bullets.
The original Berger target bullet is now their Hunting bullet.
Your understanding is spot on I remember when Berger did this, I was a member of Long-range Huntin .com when Berger made a post saying as much.
