Ok, hit a doe today right before dark and need some help. Shooting Gator 100 mechs. Doe was 25 yards away, broadside, slightly below me (I was hunting from ground, doe was standing in low spot). Clear shooting lane (she was in a field). Heard unusually loud thwack when arrow hit deer. Arrow appeared to be hanging from deer either above or slighly behind and above shoulder. Followed good blood trail for 20 yards to edge of woods where I found arrow.
Arrow is covered in blood, hair, and white and pink tissue for about 6 inches. Lots of pink tissue inside broadhead. The hair is mainly white. Blood is dark red. The "left" blade is missing, and a small dent is in the arrow on the "left" side about 4 inches back. I would guess I hit the shoulder blade or possibly the spine, causing the blade to break and the arrow to dent. I am not an experienced bowhunter. I feel sick about the lack of penetration; I had an excellent opportunity and it looks like I didn't make a good shot.
Decided to wait til morning to continue blood trailing as I didn't want to push the deer. Am I likely to recover this deer or was the shot likely non-fatal? Thanks for your help and I will report back.
