Last night, with about 10 minutes of light, I used a 100 gr. JaK-knife. The shot was 17 yards. From 20-feet high. Using a Ten point extreme crossbow. A double lung shoot. Cutting off two ribs going in and one one the way out through the shoulder. Blood trail was immediate and easy to follow. Next to a large swamp, usually very hard to trail in. He still managed to travel 100 yards. Thanks to a super tough head, large cutting diameter, and field point accuracy, the hardest part was dragging him out. Thank You , stan P>..i know it looks like a doe, but both antlers were broke off!
