From the Archives (the part I haven't updated yet) :Browning barrels will not work in Remington or Savage, and vice versa. The big stumbling block is the ejector. On the Remington and Savage the ejector is a single hook brazed to the rear of the barrel extension. On the Browning the ejector is a pair of hooks. The bolts of each are slotted to fit their proper ejector. The wrong barrel won't clear the bolt and the ejector will get hammered if you try. Barrels of the Remington and Savage shotguns have a limited potential to be interchangeable, due to the shell stop cam cuts. The cam cuts are beveled notches on the exterior of the barrel extension. They work the cartridge stop that prevents a second shell from feeding out of the magazine.Slight variations of dimensions through the decades allows some barrels to work in both models. Like I said, "some". Most do not. The only way to be sure is to try it. Frist, try feeding dummy rounds, and if that works then test fire. The best idea is to buy the correct barrel for your gun.Information from Gunsmithing: Shotguns, by Sweeney.
