If that is the case, then the C:B is 39/30, or 1.3:1.

Edit: Since the chamber and barrel are the same size diameter, it becomes unnecessary to calculate the volume to obtain this ratio, however, it should be noted that this is just an approximation. A more accurate way, as mentioned earlier, is to use the fluid method to obtain the volume, then divide the chamber's volume by the barrel's volume.

The performance should be wonderful :wink:

Some swear by a C:B with pneumatics but it all depends on the pressure, air flow, and stuff like that. C:B is more relevant with combustions and hybrids.

That range is possible, but I would question as to how you found your ball (assuming that you used the rubber balls from the other thread). From looking at the map, it appears as if the ball would have landed on the roadway, which appears to be blacktop. Blacktop is hard.

Assuming you shot at an angle, the ball would have hit at an angle, causing it to bounce into the trees.

i apologized already and i did have a very relivent question about how the blowgun is attached to the piece of pipe. people usually just zip tie it on but this looks very sleek and i would like some details on it.
