I know how you feel, I shot a doe on Thursday night, complete pass thru. Went out Friday at sun up and looked for about 4 and a half hours. She lost a ton of blood, most of right away, and then after 100 yards it gradually stopped. I cant believe that they can lose that much blood and we cant find the deer any where. I was even on my hands and knees looking for blood. Good luck finding him if you go back out looking. Keep us posted.
