HELP - Who re-regulated my Sabatti 500 NE ?

Hello all,

I just bought a very nice Sabatti 92 Safari Deluxe in 500 NE caliber. It has been re-regulated, but there was no target or any indication of "who" did the work. It appears that whoever did the re-regulating also tuned the triggers, (smooth 5-1/2 and 6-1/2 lbs) and also upgraded to a NECG recoil pad.

The wedge has been left protruding, so this may be a clue. I know that JJ does this on occasion, having done so on one of my other doubles that he regulated for me.

I've talked with Ken Owen, and its not his work. Not sure who else does Sabatti re-regulation. I've been told not too many gunsmiths will re-regulate them because the barrels lack a wedge and are hard soldered.

Anyone have any suggestions? I'd like to find out what ammo its regulated to before going through a lot of trial and error.
