Hang out with my uncle for a while.
He shoots .33 Winchester, .35 Winchester, .348 Winchester, .405 Winchester, .25-35, .32-40, .38-55, .22 Savage Hi Power, .222 Rimmed, 6.5X54, .225 Winchester, .303 Savage, 9.3X74R, .44 Colt, .45 Schofield, .450 Adams, 9mm Largo, .30 Luger, and a 24 gauge shotgun.
I'm sure I left out more than a few oddballs, and it's not to say that's all he shoots. Most of his hunting is done with a 30-06.
