A large exit hole with Accubonds is NOT the norm, slightly larger than calibre is my experience in everything from 25 cal, 27, 30, 33 & 37.
This is why they penetrate so deeply and cause a large permanent cavity where it's needed........in the vitals.
I bet those 'pencil holes' were on DEAD animals, and not one's running away.
Anyway, there's no 'wrong' bullet, only wrong 'placement'.
Cheers.
