My wife and I have killed quite a bit of game with the 140 Accubonds with good results.

This year I had a moose tag, and decided to switch to copper for a little more penetraion. I used the 139 GMX and it worked well, but I don't think the jump from the accubond was necessary.

Luckily my gun shoots them both well at the same point of impact, so I can switch back and forth. I have a very good elk tag as well that I'll be hunting this weekend, and I'm not sure which round I'll use. I'm very confident with either.
