Why your 12 ga browning auto shotgun keeps jamming?

1. Dirty or obstructed chamber. A dirty or obstructed chamber can prevent the shell from fully chambering, which can cause the shotgun to jam. Clean the chamber thoroughly and ensure that there is no debris blocking the shell from fully seating.

2. Worn or damaged extractor. A worn or damaged extractor can fail to extract the spent shell casing from the chamber, which can cause the shotgun to jam. Inspect the extractor for wear or damage and replace it if necessary.

3. Weak or broken recoil spring. A weak or broken recoil spring can prevent the shotgun from cycling properly, which can cause the shotgun to jam. Inspect the recoil spring for wear or damage and replace it if necessary.

4. Incorrect ammunition. Using the wrong type of ammunition can cause the shotgun to jam. Make sure that you are using the correct type of ammunition for your shotgun.

5. Loose or damaged magazine tube. A loose or damaged magazine tube can cause the shells to feed incorrectly, which can cause the shotgun to jam. Tighten the magazine tube and ensure that it is not damaged.

6. Incorrect gas settings. If your Browning auto shotgun has adjustable gas settings, make sure that they are set correctly for the type of ammunition you are using.

If you have checked all of these potential causes and the shotgun is still jamming, you should take it to a qualified gunsmith for further inspection and repair.
