Really appreciate the great comments. SIL and his nephew (borrowed his CVA) both got a deer with the PB 245 Aerotip. Deer dropped on the spot! Bullets also went through but had some copper fragment off. Since I won't get a shot longer then 140 yards (I'm sighted in for that) I'll probably stay with them and just tinker with the sabots to see how they group.
So for all who shoot the bullets with sabots, what's your choice and why? Have you tried different bullet/sabot combos Birch? I assume you have since you have that great "deal" with your friend.
