Have I decided on calibre? No, although the 9.3x74R remains a firm favourite. I still have a soft spot for the .375 H&H Flanged though.

Yes, I will reload for this gun so in theory availability of factory ammo is not so important. However, reloading for doubles is not straightforward and I may need to rely on the factory load the rifle is regulated with.

In the case of .375 H&H flanged there are few choices. I can only find Kynoch and Norma and the Norma offering uses heavy jacketed Woodleighs which would not be my choice for thin-skinned game.
