This is a compilation of the most common shell sizes used in the firework industry from the small all the way through to the massive 48" shell that's launched in Japan each year. There are other sizes of shells available and other countries do use shells with slightly different calibers and if anyone has some links to unusual sized shells great or small i would love to see the videos.
Please watch to the end for one amazing powerful finale to includes almost every size shell available but excludes the 48" shell.
