Back in Nov of 2010 at my oldest sister & brother-in-law's farm in upstate NY....
125 acres all to myself. Free use of an ATV. It was awesome, except for NY State's crazy laws.
Getting to the point: I was up in the upper pasture near the barn, and used my grunt tube and a 6 pointer came rumbling down the treelined hilltop. Actually he was a 5 pointer, with a busted tine because he got his a$$ kicked by a bigger buck, who snapped part of his tine off in the fight. He was roughly 125 yards away, looking around wondering what buck was on his turf. He was used to farm tractors, barns, ATV's, so he wasn't spooked. I raised up my Savage .308 rifle and put him in the crosshairs. I said a silent prayer and gently squeezed the trigger.
BANG... FLOP... DOA right there.
Buck had no idea what hit him. Upon field dressing, my brother-in-law and I quickly realized that I not only dropped the buck with one shot, but I actually blew the Aorta right off his heart with a 165gr Nosler Ballistic Tip!
