Did you know? Barrel diameter affects pressure:
Choosing the right tool for an application requires an understanding of the relationship between the Force (thrust) created Drive System and Pressures (PSI) within the Material Containment Unit (MCU).

For example: a Bulk gun with a 2⅝” diameter generates 700 lb force, however, if the diameter increases to 3⅜” the force drops to 375 lb force; basically the initial force generated by the drive is spread out over a larger area (diameter) and so the pressure drops accordingly.

Note the decrease in pressure as the barrel increase in size
