Amazing to me how radically different bullets perform for different people. My son has shot quite a bit with the 80gr TTSX in a 25-06. Even a brown bear. Total penetration and mostly DRT.
I have only watched about 30-35 Accubonds used and have yet to see a pass-through, even on smallish stuff. Watched a Kodiak bear take four 270gr Accubonds in the ribs from a 375H&H... all were caught.
A lot more questions than answers...
Size/attitude of the animals being shot? Hasn't your son been primarily shooting things like moose, caribou, and bears in the shoulders?
I will say that the culling report has a very similar nuance to what would be expected from the NZ website that reports all of his bullet experiences/expectations.
Basically, a soft-fronted tough-butted heavy-for-caliber C+C bullet started at 3000 or more kills ungulates very well. Everything else becomes a compromise from that ideal.
