Unless one is careful when they freeze powder or powder-like propellants, it is easy to get condensation from the atmosphere this, when thawed can adversely affect propellants.
The problem is that mortars are designed in such a way that to operate them, the projectile and propellant bags are held above the opening of the tube, then dropped. Anyone who has fired a mortar knows that it does have to be lined up kinda carefully or one risks hanging the round - bad thing. |
What would be critical temperature for performance of mortar shell? I'm asking because Finnish Army have order to defend country no matter if temp is +40 or -40 degrees celsius and we use mortars, a lot... mortar here... mortar there... few more over there...
