John, On the 270 in Namibia, before taking one I asked multiple outfitters(5 or 6) about the 7 millimeter bore diameter rule. Remember Namibia has had a close relationship with Germany. The Germans are very familiar with the metric system. In responding to my inquiry they all looked at me as if I knew nothing and said of course the bore diameter is at least 7mm. They mumbled “Dunkoff” e.g blockhead.
There is a lengthy discussion on AR about a wildcat made by necking the 375 H&H so as to shoot .423” bullets which the developer has named the .404/375 H&H. According to Krieger the barrel’s bore and groove measurements are .413”/.424”. I understand it is to duplicate original .404 Jeffery ballistics using the namesakes’ .423” bullets. Senseless. It should be called the .413/375 or the .423/375. Rick
