Does this gun have a retailer's name stamped on it? I ask because many of the Simsons with 70mm chambers were intended for export.
I'd leave the gun as-is and buy some spreader wads (or cartridges) if it has the (normal) very tight chokes. Doubt if the chokes or forcing cones will increase the recoil noticeably, especially if you are using it for hunting.
A great gun by a great German company erased by the Nazis and then the Communists. Hope the Simsons are still doing well here in LA! Unlike the Nazis, we were glad to have them. (I doubt if they would have done much better under the East Germans if by some odd chance they had survived Hitler).
