Pilgrim
Welcome to the forum.
Take a look at the Chapuis Double rifles. I have one in 9,3x74R. They also make one in 375 H&H. If/when I get an H&H double it will be a Chapuis. I have been very happy with mine. They are very easy to scope. Heym and Krieghoff are also brands to consider. If ordering new I would get the scope mount fitted to the rifle from the start.
For any game normally shot at 200 yards and under I MUCH prefer a double rifle.
The ONLY bad thing about getting your first double is that you will want more of them.
