I posted in the crossbow thread too but no responses. My dad shot the bucks of a lifetime on Sunday. The deer went 200 yards and tipped over and with the snow it was easy tracking. But when he went and looked for the bolt he found 75-80% of it at the impact location with only 1 blade left on the head. The other two were blown right off. The arrow was laying on the snow so they didn't blow off from hitting the ground. The fletching only had blood on about 1" of the 3" vanes and was laying farther away. Temps were single digits below zero with wind chills in the -20 range. The hole in the deer is between the size of a quarter and half dollar. It honestly looks like sharp field tip killed the thing. He didn't hit any major bones. Both holes are right behind the front shoulders. Anyone have an idea of what happened. He said the sound the arrow made when it hit the buck was very loud. But it was also his first archery deer so he might not have expected that crack from the arrow hitting home.
