I don´t understand why you pondering so much this one caliber and it´s usefullness. At the same time one cartridge maker from USA releases whole family of new calibers. I don´t speak out if it is sensible or not but one new caliber which is very useable for example those Swiss hunters is IMO a positive thing. It´s parent case is very common .375 H&H so making these ammos is quite easy and probaly quite cheap too.
