I was in the Wal-Mart in Durango, CO, a few years ago and a guy came in and bought a box of 300 Win Mag ammo. He happened to be parked next to my truck and I asked him if he'd seen any good bulls, it was elk season. He said that there was a great bull coming onto his BIL's ranch and he was going to shoot it with his new Weatherby. Since he bought 300 Win Mag ammo, I was thinking Vanguard, but he showed me a Mark V. I looked at it and noted that it was chambered for 300 Wea Mag. He'd never shot it, never zeroed the scope, didn't know that 300 Win Mag was a totally different cartridge. I pointed the difference out to him and he shook his head as though he understood, but I sensed that he really didn't understand. I wished him good luck and we both went on our separate ways.
