Here is a video from Terminal Ballistics Research showing three kills using DRT Ammo. It expands and sheds weight resulting in fast, clean kills. The shots were taken at 100, 375, and 605 yards. You can see how the bullet behaves terminally as the velocity drops. This is a good alternative to all copper bullets that retain 90% of their weight when non-toxic ammo is required or desired:https://www.youtube.com/watch?v=Qvge3tA5bXo&feature=youtu.be
No knock on other non-toxic ammo. This is just an alternative that behaves differently in terminal performance, so guys have more options.
