I love German shotguns pre-War. I have several and wish to go hunting with them. They are chambered in 2 1/2 to 2 5/8. I was able to buy factory loaded, Gamebore 2 1/2 12, 20, and 16 gauge shells out of England. They advertised its safe to shoot in old doubles. I think it runs 8600 psi. I am wondering if that’s pushing the upper limits of these old guns. I have 1 oz 20 and 16 gauge loads from them and 1 1/8 12 gauge . What does everyone think?
