Shell 130 mm HE
The 130 mm, gun M-46 is a long range medium gun and is capable of direct as well as indirect laying fire. The gun is designed to :
i) Destroy/neutralise hostile artillery including self propelled artillery.
ii) Fight the enemy heavy tanks.
iii) Destroy enemy pill boxes and strong field works.
iv) Fire at enemy rear areas and concentration areas
The ammunition is of Q.F Separate type, permitting the adjustment of propellant charge.
Action Of Fuze


On firing : On set back, the upper arming collar sets back compressing the arming spring and closes lateral recesses in the inertia pellet sleeve thus preventing the centrifugal bolts from moving out of the groove in the inertia pellet, thereby locking the inertia pellet during the passage of the projectile in the bore of the gun.


During Flight : the arming spring exerts itself and pushes upwards the upper arming collar clearing lateral recesses in the inertia pellet sleeve, the centrifugal bolts fly outward due to centrifugal force thereby disengaging from the inertia pellet. The fuze is armed. The inertia pellet is held away from the striker by the striker spring until the point of impact.


On impact : The inertia pellet overcomes the resistance of the striker spring and moves towards the striker. The detonator in the inertia pellet gets initiated. The flash passes through the diagonal channel in the striker holder, through the four half circular vertical grooves on strike head and onto delay composition. After the delay composition is burnt out, the flash initiates the detonator in the magazine which in turn initiates the charge in the magazine. This charge in turn detonates the bursting charge in the shell.
