I’ve got one built by Dakota. If you want a rifle the same size as a .375 H&H that shoots a .40 caliber bullet it’s a good choice. A .416 Remington Magnum is probably a more practical choice but I believe the .400 H&H is a superior case design. Getting the correct diameter bullets is a bit of a challenge but if you want properly marked cases Quality Cartridge has them. Of course you can easily neck up .375 H&H cases, they’ll be a little short. I used mine on 6 Cape buffalo.
