I don't know the longest I've ever shot. I'd go skeet shooting with daddy in a league. Then we'd go over and shoot pistol. He wanted to take me deer hunting so we practices rifle on the range. I went with him and my aunt and uncle but I didn't shoot the deer. It was too big and majestic. My dad was mad at first, after I started crying, he understood.
But, back to the distance. I don't think I ever shot more than 50 yards. 300 yards must seem so far.
