Well We have a older gentleman on our lease who once could stack the whitetail up every year and do some fine shooting at the 4 to 500 yard range . He is now in his late 70’s and can’t quite shoot the 7mag he packs very well any more. So the guy’s and I have decided to purchase him something more recoil friendly and gift it to him just before season opens. We still want a caliber able to make a clean kill at 3 to 400 yards . The calibers we have come up with is 6mm ,243,25-06 . What is your thoughts gentleman?
