I was extremely hopeful in the 180 ELDM but they just are not consistent across multiple elk, I lost an elk this year, I'm hoping I misses but I don't see how, 4 of us followed the herd the whole day and found not a drop of blood or anything but we did find a dead cow later in the season, no way to tell if it was the one I shot at but I'm suspicious, I haven't missed an elk in 10 years. I know another group of guys ran them that kill a lot of elk and they had some blow up so bad they didn't get into the vitals on hits that should have been easy, then some performed awesome. The 195 Berger is a the same way, one elk you'll blow a hole through the next it goes hay wire. I had to pack two different bullet one as a back up to these and I'm just over that.
I've seen better that 100 elk shot with the 270 cal 165 Matrix one shot kills and the few with the 170 Berger's have all been very consistent.
