I think its a fantastic bullet in 6AI, I use it for the same purpose, PD's. I have found that I get get very reliable expansion at all ranges I can shoot. Farthest kill with it is 700+ I have found it is pretty dramatic on large jackrabbits.
However, I dont get near the explosive splat factor as I do from smaller bullets going significantly faster at closer ranges..
I really like the bullet and its price for shooting in my 6AI.
