1. Flanged for sure

2. 450...yes as Hornady is making the ammo and the gun could be built trimmer than a 470.

3. Not really as this market is filled up with cheaper European guns.

4. If the quality and style is good I would buy one or two.

5. I would prefer chopper lump barrels and would pay more to get them.

I would love to see a good quality rifle similar to a Webley boxlock double. The market exists as you would be competing with Heym, Searcy (no comparison) and that's about it.
