I have an option on a Franz Zodia O/U two barrel set in 300H&H and 20 g. I have done some research on Zodia and despite there not being much available have come up with the following: Obviously part of the Furlach guild but went OOB in 1986; generally high quality guns but the barrels are not proofed and therefore high pressure loads in the shotgun should be avoided. Steel shot is a no no... I doubt I would ever take the gun into a duck blind anyway. Now here is the real reason for my post. I would like to have a third barrel set made in either 375 H&H or 450/400 NE. Which caliber would be recommended and who could/should I get to do the work since Zodia is no longer in business? I would think the best match would be provided by another Furlach gunmaker. What can I expect to spend on this third set of barrels? Many thanks and any and all comments are welcome.
