I will answer that post at 40 yards with a 6.5X55 BT drop a 9 piont in its tracks when guting it I found that there was no heart and no liver they were jelly.
last year at 275 yards drop 6 point in its tracks what more can be said.
Just my opion I dont worry what someone wright in a book I go by what works for me.
BTs all the way
