Hi Oddione, this is the same deal as you asked me about the alsakan, the p-14 is a standard length and you can't use it for a magnum length like the H&H it is just to short.
PS I don't think that is Ardent in pictures in the link you posted as that guy lives in northren California. I could be wrong though but my dogs tell me that has never happened before LOL.
He's definitely in one of the pictures.
So tell us Ardent, have I stumbled upon your hunting partner's thread by googling .375H&H conversions? Or are you a ninja/ghost who mysteriously appears in other people's safari hunting pics





























9.3x74R is just swell as a cartridge, but it's not a .375 H&H, is more expensive, and good dangerous game guns chambering it start at about $7,000-9,000 (entry level doubles). Plus, you'll have a hard time finding ammunition.
