Are the notches on choke tube standard or are they different with each gun manufacturer? Any help would be appreciated.
There are a few different reasons for the notches on choke tubes. One reason is that it allows for better gas seals. Another reason is that it helps to prevent wear on the tube. Lastly, it can help to improve the accuracy of your shot.
When choosing a choke tube, you want to make sure that it has the right constriction for your needs. If you are using a shotgun for hunting, you will want a tighter choke so that you can get a narrower pattern and take Down the game more easily. On the other hand, if you are using your shotgun for skeet shooting, you will want a looser choke so that your pellets spread out more and You have a better chance of hitting targets.
