That's not what I said. If the short mag BT bullets are shot in moderate distances (@75yds or less) and don't impact something like bone and hit only skin area(no ribs) They will expand very little if at all and will only leave small holes on both sides of a deer. There will also be very little trauma on the lungs as well. This is not myth as some may thing?If they had hit a shoulder it would have been a different story on the expansion and trauma sustained. But everyone has a title to their own opinion.
