Remington 870 Express vs. Express Magnum. I have an older Remington 870 Express. The barrel indicates to shoot "2 3/4 or 3" in three inch chambers use 2 3/4" in all others" My question is what is my chamber. It says 870 Express and does not say Magnum however it was manufactured before they started stamping them "Magnum". Is there any way to know if I can shoot "3 inch" shells in my gun safely? The gun will chamber a 3 inch shell but I have not fired one out of it for fear of unjury/damage. I got the gun used from a guy several years ago so I have none of the orginal paperwork. Any help would be appreciated.
