One day I was going to buy reloaded ammo in a Shooting field, the salesman told that the cougar 8000 doesn´t work very well with this kind of ammo. The explanation: he told me that the rotating barrel mecanism is very delicate to the dust produced for the reloads, making the gun to get jammed and even get damaged. Also he told me that this gun is more delicate to the dirt (dust, sand, etc...) than any other gun, is this true? Because of the dirt can the rotating mecanism get jammed and even broken? What experiences do you have? thank you!
