Acceleration in the Gun Tube

The following graph shows the measured gas pressure in function of time. The point of measurement in the chamber is at a distance of 261 mm from the breechblock. The end of burning of the propellant is very well visible. At the muzzle exit of the projectile there is still a considerable pressure measured.
