My oldest son and I pulled the memory card at our feeder after our morning hunt opening day of the youth weekend. After looking at the 4000+ pictures on the card a few days later, I found out that a mature buck had been using / defending the feeder for about a month. Almost every morning and evening in the daylight but a little more frequent in the mornings. I told my son that if we were going hunt this deer that we needed to get in there super early to avoid bumping him or crossing paths on the way in. We got to our uprooted oak tree / natural ground blind at 6:00a.m. Almost instantly after we got settled in, the woods were crawling with animals. It started breaking daylight good enough to see pretty good and I hear a deer walking to our right. I eased my binoculars up and I could tell it was the buck at only 20 yards in some young beech trees. We sat motionless until the buck got past us and headed up the hill towards the feeder which we were about 60 yards from. He stopped about 10 yards to the right of the feeder and started throwing his head in the air scent checking. My son got the muzzle loader rested on top of the log. In a shaky voice, he told me that he did not have a heart shot but he said he had the lungs wide open. In a returned shaky voice, I told him to squeeze the trigger when he was ready. The woods filled with smoke! I asked him if he felt good about the shot and he said he had it right on him. We waited a few minutes and headed up to where the buck was standing. We immediately found foamy blood with pieces of bone in it. We tracked the blood for about 10 yards and it went off the side of the knob. We looked around for a couple more minutes and glanced out in front of us and there was his buck, laying on his back at the bottom of the knob. There are no words to describe how much excitement we had!!! My son had just killed his first deer with a muzzle loader and it was a dandy. He has killed several but this is his biggest... 172lb 9pt.
