I think the guy wounding deer with the 6.5 Grendel may have been using the wrong bullets. What bullet was he using in that 6.5 Grendel ammo?

I use Barnes bullets for hunting exclusively, regardless of caliber. Bullet placement is number 1, followed by bullet construction to make effective kills. I would still use a 6.5 Grendel with Barnes bullets (my handloads) if the range were out past 350 yards or so. Here in Wisconsin, shots that far are very rare though.

All of my hunting friends are using the 300 WSM with Barnes bullets, and the size of the exit wounds are twice as big as with my .260 Rem. at similar ranges. My friends have never recovered a Barnes bullet from deer firing their 300 WSM's, even when penetrating the deer length-wise.

I have recovered only 1 bullet using Barnes bullets in my .260 Remington for the past 10 years. That was this past season and it was found under the hide on the rump after penetrating the buck length-wise at about 100 yards. He dropped right there.
