The buck I killed last year was a shoulder shot at 30 yards. It went through the shoulder breaking it in half. The muzzy actually lodged on the opposite shoulder. The arrow broke instantly, i thought he was gone for sure, but he only went about 60 yrds and crashed over. My shot severed the aorta and he didn't stand a chance. there was actualy no blood trail, the meat of the shoulder clogged up the hole. i just walked off the last time i saw him and sure enough he was there, dead.
She will die, it's just a matter of time. Wait it out and start searching from the last place you saw her. Just give her time to expire. Good Luck.
