851c,
Thank you for the kind words on the rifle.

The action is all left of a Beretta Gr2 SxS 12 gauge All else is exhibition wood, custom barrels, and a nice cushy recoil pad.
I do not know whether Beretta sold factory made SxS 45-70 Double rifles.

I bought this rifle from the estate of a gun maker who made it for himself and hunted deer with it for several years. He also made my Simson Suhl .405 WCF DR and knew that I wanted a 45-90 DR, but never told me that he made and was shooting this Beretta. He used medium velocity 300 grain hand loads and they shoot right through 300 pound hogs. I have the planning specifications for both rifles and they both handle and shoot just right for me.
