There are many factors to consider when choosing a choke tube for trap shooting. The type of gun, the type of ammunition, and the shooter’s style all play a role in determining the best choke tube.
For example, if you are using a shotgun with a barrel length of 30 inches or less, you will likely want to choose a full choke tube. This will provide the tightest shot pattern and the most powerful shot.
If you are using a longer barrel shotgun, you may want to choose an improved cylinder or modified choke tube. These provide a more open shot pattern, which is better for long-range shooting. I think it is important to experiment with different types of choke tubes to see which one works best for you.
