I took a doe last Friday with a game tracker expandable 100gr. I was on the ground and I hit her high, just above the lung area. The arrow didn't pass through but there was an initial blood flow upon the hit. She lunged forward and broke the arrow off. I noticed the blood flow lessen almost immediately as she walked about 30 feet off and stood behind a tree for about 40 seconds then trotted down the hill. I retrieved my arrow and waited. I had bright blood but no bubbles. I heard what i thought was her about 3 minutes later fall down the ravine. After about 45 minutes I started tracking and lost all blood trail within 30 yards. I could see roughed leaves and headed in the general direction very slowly. I found her at 75 yards. I hit her in the void above the lungs but fortunately found her. She bleed internally rather than on the ground. It was my first bow kill and I'm not sure but i think she ducked a bit. I shot her at 12 yrds. I barely missed a double lung. My nephew shot a doe just above the heart the other night, I took the deer to the butcher so i saw it, and it traveled over 300 yards. sometimes it is hard to say how far they will go
