Hi again folks, I have a nice 1900 Remington KED 12 gauge that sat against a kitchen wall corner for a good half century, hardly used or fired at all. I've known about this 12 Ga. myself just about as long. I went to school with the original owners son, we graduated high school in 1959. The overall condition of wood, checkering, and screws are as good as could be hoped for, the metal finish has faded from sitting in the sun all those years. My question is, "what might the chamber length be, & what would be a safe & comfortable load to use in this SxS?" I know this is a difficult question, without seeing the SxS, but I would like to shoot it at Skeet and maybe some Cotton Tails. Tanks in advance, Martin 1940D28
