Never know who you meet. Several years ago, was in a shop in Tidewater VA. Youngster came in, and jumped into a conversation about .300 Win Mag. He badmouthed the .300- there are so many other better rounds, it was just an over hyped 30-06, child of Winchester marketing, etc. He left shop without being introduced to gent that was discussing 300 Winny loads with shop owner.
Carolos Hatchcock. In addition to his fame as a Marine sniper, had won the 1000 meter Wimbleton Cup Championship. Shot a perfect 10X- with a .300 Winchester Magnum.
