I just pulled my dad's old Remington 11-48 (Serial 5020700 - Manuf. May, 1949) out of the closet after about 20 years and want to start shooting it again but I'm not confident on how to set up the recoil system. I've seen info on the web about the model 11 but I think the 11-48 is different. The handbook PDF isn't all that clear. From the trigger forward, I have the Recoil Spring, the Recoil Spring Ring, and then the Friction Piece (which stays inside the Barrel Guide.) The handbook mentions a "Felt Wiper Ring" inside the Recoil Spring Ring but I don't have one of those. The Ring has a heavy load/light load option with arrows (I assume they are supposed to point towards the front of the barrel). Other than a nice light coat of oil, any suggestions on how I should change this set up to go shoot some clays?
