Gorgeous gun, & great advice!
Mulling one of these with that stock in the longer barrelled, longer cylinder, 18-20 fpe version. But the exact name of that specific model has proven elusive, as have the cylinder volume & approximate shot count of that version. Have inquiries with a couple of vendors to see if they can provide that info, & have said version available.
Considering this vs. a Daystate Huntsman Revere Safari edition (when it finally makes it across the pond) or Air Arms S510 XS Ultimate Sporter Xtra FAC. Was able to find specs for the Daystate easily, a little tricky with the AA but think I have it down. The Weihrauch has been hard to pin down.
One thing for sure, the full nomenclature doesn't exactly roll off the tongue with any of them
