Re: How can you tell if a remington shotgun has a damascus barrel
I did mention corrosive priming in the second paragraph.
It is often mentioned that those barrels passed proof and therefore are OK. (There are no proof laws in the U.S., but the top makers - like Remington - did and do prove their guns.) But the barrel that passed proof in 1890 is unlikely to be in the same condition today.
Even if some Damascus barrels do stand up to proof loads (I presume with old-time proof pressures), that does not mean an identical barrel made at the same time - or even the one on the other side of the gun - will also stand proof. There are just too many unknowns in dealing with those old guns.
