I have been very fortunate to grow up here in southwest Virginia in a hunting family. My father started me hunting at 8 years old with a winchester single shot .410. I'm 37 now and still get goosebumps at the sight of a deer. I am not as you would say a trophy hunter but more of a meat hunter. Over the years I have harvested many whitetail for the family freezer and have made some observations some of you may find interesting. I have had the opportunity to hunt with many different calibers of guns. I have used the .243win,30-30,45-70govt.,.35rem,7mm Rem. Mag., and my current toy .300 Weatherby. I may not make many friends with this next statement but here it goes. In my opinion there is no such thing as knock down power. I have witnessed the .243 drop deer without so much as a twitch at 200 yards and have witnessed a nice buck take a 300gr. partition through both shoulders,heart and lungs at 40 yards but still run nearly a quarter mile before collapsing. This year alone I have taken two deer with the .300Wby. The first one was broadside at 130yds. The 180gr. Nosler Accubond entered the right shoulder gelatinizing the heart and lungs and exited behind the left shoulder. This deer still managed to jump a fence and run 50 yards before giving up the ghost. The second deer was 330 yards quartering away. Once again the Accubond entered near the last rib and traveled through the heart and lungs before coming to a stop in the far shoulder after shattering the bone. This deer went about thirty yards before succumbing. Now my brother is a .243 man all the way. Saturday I watched as he harvested a doe at 215yards on the dot. The shot was a little back but guess what. That deer never twitched. Dropped on the spot with barely taking out the back edge of the lungs. How's that for knockdown power.
