Ben,
Krieghoff is making a fine single shot break open action with an excellent integral scope mounting system (not inexpensive) called the Hubertus- accuracy in an example I shot in 9.3x74R was exceptional.

Mark,
Interesting notes on the Merkel, I had considered one (and now probably can forget it) and appreciate the feedback. Was the receiver made a an aluminum alloy or steel?

Best Regards
