i shot a deer a few years back using a muzzy two blade and hit back near the rear leg and messed her up so she couldnt run then i shot her again in the ribs slight 1/4 too me but i wanted to put another one in her and the deer layed down and i sat and watched it for about ten minutes looked like it was gonna die and i only had one arrow left in my quiver. i turned to watch this buck and turned back and she was walking off with two arrows sticking out the other side of her. 3hrs later i went looking for her and found both arrows and decent blood within 50yrds and looked up and she was walking off slow so came back about 10hrs later and not one drop of blood from the last spot she layed down. i looked for along time with three other guys and did tons of drive one that area that year and never found anything. that was the last time i shot fixed heads and also the last time i ever lost a deer. one other deer i shot before that one that year had poor blood trail. i know there have been plenty of deer taken with them but why chance it.
