I was prepared to buy a 375 H&H double one time from a dealer that knew me well. He flat out told me not to do it.
He recommended a 9,3x74R instead. I have been using a Chapuis double in 9,3 for about 4 to 5 years. I like it very well and recommend it highly. I prefer it to any 375 Bolt for DG. I have also shot a 470 Chapuis. It shot and handled well, but I prefer a British double in 40 cal and up.
I handled a Perugini & Visini in 9,3 at the Dallas Safari show that felt real good, but you cannot go wrong with the Chapuis.
You can get the Krieghoff in 375 Flanged.
