Hello

I am being offered a Holland & Holland, Royal .400 Nitro Express (the old 3 inch black powder cartridge converted to smokeless powder). The rifle is nitro proofed.

The double rifle is in very good condition. I do not intend to use it for dangerous game but need to know if any one of you have had experience with this caliber and what do you think of it as a medium game caliber.

Regards
Aziz
