For anyone who may be interested (and is able to read german ) http://download.ble.de/09HS023.pdf It was published today afaik. I'm reading it right now, can't judge the study's value. ps: Summary: Typical german game runs less far when hit with bullets penetrating atleast 30cm and sheading 100J per cm of ballistic soap in the first 15cm of the test medium. We didn't figure something like that for ourselves. Seems to be rather a foundation for government regulation of hunting ammunition without new or practically applicable information for hunters who do understand external and terminal ballistics a bit.
