I did not hear the arrow hit my first deer (Doe). It went between the ribs on entry. Double lung shot, nicked a rib on exit. I have heard many since. It was a long time ago, 1977. My first bow was a Jennings model T 50 lb pull. 2018 Gamegetters with 100gr wasp broadheads. I missed the first Deer I ever shot at a few years before. It was a Nice 8 point Buck. I was new to bow hunting. He walked in to about 25 yds. I started to draw and he Stopped looked straight up at me. I froze at mid draw. He just stared at me. He pawed the ground trying to get me to move. It seemed like our eyes were locked on each others for 5 minutes, but it was probably more like 30-45 seconds. Any way, he had enough of me and bolted. As he lept away I let the arrow fly. It went right over his back. That image is burned into my memory. I learned a lot about bow hunting that day. The hard way. Sometimes thats the best way to learn. Never got busted on a draw since.
