I don't understand why people are suggesting small calibers such as 7mm and 30.06, that Are ment for bolt rifles in the first place. I am mean you don't spend a great load of money on doublerifle, and have it chambered, in a caliber that you can get in a cheap gun...

No choose a caliber that have history in double's. And you did!! 375h&h flanged magnum nitro express, love that long name, and its The caliber i am gone have in my first double.

Krieghoff, they have adjustable wedges in The barrels on The 375 on big five version. And The standard version you Get in norway is without any engraving, it actually makes The gun look better.
