I've shot 7 fallow deer, 4 bucks and 3 does, with 139gr interlocks and they've all have exited leaving very dead deer.
I'm running them over 44grs of AR2208 (Varget to you guys) and they shoot well out of my Rem700 7mm 08.
If I have to go to just one bullet for that rifle, the interlock would be the one.
