Been toying with the idea of a double rifle on a Greener, although just thoughts at the moment. I think I have just about read all there is to read on this subject but I have a few questions for those who know. What if any full Nitro cartridges are suitable for this action? I was thinking 450/400 but I dont know what pressures this cartridge produces or what the action can handle. The .577 BPE sounds so much of a good thing, and would be a great buzz to play with. But with the Fat Lady having so short barrel lengths would you still achieve full powder burn? And would it be sensible to maybe add an inch or two of length, or would this be going to far and losing pointability? (Is that a word?) Lastly is there anybody in Australia that is willing and more to the point able to make a set of barrels for a Greener double rifle.
This is not something I would look at tomorrow, as I have too many fingers in too many pies right now. my Brno 602 is getting it's barrel and sights fitted at the moment (.404). And I can't wait to get it back so I can finish the stock on it. And I have just bought a nice semi-inletted stock for a 98 Mauser which I want to build into a .338WM as I just love this round and what it can do, I have one already but want another (is that wrong?).

Cheers,
Bill
