I've been playing this game for a couple weeks now and I've noticed how the gunpowder in the game is very unrealistic. Modern day gunpowder (smokeless powder) burns slowly and doesnt explode unless if it is in a closed environment. I think it should be the same in this game because if you ignite the gunpowder in an open environment, it immediatly explodes instead of burning.
I also think they should add blackpowder, which was commonly used for muskets and early rifles. This type of gunpowder created smoke and also burned much quicker than smokeless powder. But it also was corrisive to metals.
Just expressing my ideas that could possible be added in future updates in this game. Also, the pressure created by the current gun powder is very unrealistic, it can barrely move particles like sand.
