I saw a video clip of an Australian PH on here somewhere, where he mentioned his rifle was a .465 H and H. Can't remember where I saw it though. It's all doable, just at what cost? I've seen the bullets for it here, but nothing else.Well the two cartridges by H&H came out at the same time. Reasonably is the key word here and I don't know where you can get the gear unless someone is willing to share costs which would be the way I'd go or just steal stuff from a mate which we do from time to time. Obscure is expensive but think of the bragging rights: "Oh you've got a .400 H&H? well I've got the .465 H&H suck on that!"
