You'll do fine.
I've shot multiple deer to 350 with my 85s and all were 1 shot successes. (I am running considerably higher velocities though)
Not gonna lie, I'm not comfortable slinging 85s out of a 6.5. I didn't buy a 6.5 to shoot 6mm bullet weights. There was a fella on here about a year ago that shot a mule deer with those 85s at 350 or 400 yards i cant remember exactly and if I remember correctly he had to shoot it multiple times. Just a good example of shooting outside the limits of that little bullet. Looses poop really fast. That's why I was considering the 110. Theres a balance between speed, and weight/energy. I dont subscribe to extremes. I like middle of the road, and balanced.
