I've only killed 4 elk with 180 gr. Bergers out of my 7mmSTW - 3 never took a step, justed crumpled where they stood. The only elk that wasn't DRT, was a cow that was shot as she was running about 80-90 yards away, after the shot she maybe went 30yds before she crumpled up, and she left the biggest blood trail I've ever seen left by any critter. Looked like somebody filled a 5 gallon bucket with blood and flung it down the trail - Ray Charles could of followed it. Two of the 4 elk had exit holes, both being close shots of less than 100yds. As far as the Bergers go - I love em, they do the job and they're accurate as hell.
