Feck, Bergs that's one serious piece of shit! when I see things like that I remember when we used to go down the range with the old Winchester black powder and .44 Italian copy of the Peacemaker.
Loved it until the crazies killed kids and passers by, it stopped all that.
Serious shooters don't have much choice nowadays.
One of the reasons I left UK was that my Browning Hi-Powers were confiscated after Dunblane. This is a Blaser Tac II chambered in .300" Winchester Magnum. The calibers are interchangeable and my adorable wife also bought me a second barrel and bolt-face in .338" Lapua, Takes less than a minute to swap barrels.
