Pre war 16 gauge Browning Auto 5's had smaller ejection ports. The purpose is up to dispute, but most argue it was to limit rain and debris from entering. The correct way to measure the shell size is to measure from the face of the bolt. If the bolt is below the opening by 1/4 inch or more, you can use 2 3/4 shells. Another clue will be the barrel. If it is marked with "2 3/4 shell" you can use a that size shell. Some 16's were assembled using mixed barrels and barrel extensions. I have a very old model that has a sliding ejector with a short barrel extension.
The number one cause of shells failing to be ejected clear of the port is a combination of the extractor on the bolt needs sharpening or the type of shell. Shells with crisp, flat rims will eject properly. Try a Win. AA or Remington STS shell. I have all kinds of problems with Multi Metal, Fiochhi and other lesser cost shells not clearing the opening.
What is the difference between spider and crab?
A spider is NOT an insect. It is, well I don't know what it is, a thing that can make webs. It also has eight legs! Some of them can be poisonous when they bite you. I think a Black Widow is poisonous, but maybe it isn't. A crab is a crustacean just like lobsters, crayfish or crawfish, shrimp, krill, and barnacle. It also has sharp pincers and always moves sideways. ( Trust me, I know these things from swimming in the ocean at Junior Lifeguards.) Bam! I just answered your question. I am smart aren't I? : ) ( I would do emoji but pcs can't read it.) It will just be a boring square.
