I have been told by a WW2 veteran that this fires at roughly the same distance and speed as a real bazooka.
The hopup educes a backspin on the tennis ball also known as the Magnus effect. The ball leaves the barrel at somewhere between 220 fps and 310 fps, depending on pressure. The backspin keeps the ball on a flat level trajectory until it "drops" and comes to almost a complete stop. It is really wild to watch the shot from the side. The ball leaves the barrel, then slows down, and falls. It almost looks like it is in slow motion. You can easily catch the tennis ball with your hands beyond at 75-100 feet.
World's largest hopup. (That I know of.)
