I was shooting a 300 Win. Mag. stoked with Federal's 200-grain Nosler Partition load. I squeezed the trigger and before I lost sight of the moose in recoil, I watched him tip over. I couldn't believe one round could take him off his feet so quickly. Steve and I swapped high fives, then quickly moved down to where the bull had fallen. Walking up on the downed bull, Steve and I couldn't believe we had misjudged him so badly. He was way over 50 inches wide (he later taped 69 1/4 inches wide), with four points on one brow tine and three on the other. A large-bodied moose will weigh about 1,500 pounds, but we estimated this bull would have gone an honest 1,800 pounds.
