Listen to @Formidilosus on the Shoot2Hunt Podcast. ELDX or M if lead. I've been using DRT bullets and they (for me) have been exceptional this season, one-shot kills with dramatic trauma at 40, 205, and 420 yards on three different animals. The later two were bang-flops, the first went 3 steps. That is extremely annecdotal but I've been happy and I wouldn't hesitate to recommend highly fragmenting bullets.
