I'm somewhat into .300 magnums. I have a second year of German production, Weatherby Mark V in Weatherby Magnum. A have a Sako Hunter in Walnut in .300 Winchester Magnum and a Remington 700 Stainless in .300 Remington Ultra Magnum. The RUM is a shoulder killer. The others are simply shoulder cripplers. A .308 is a pussy round compared to any of them.
