Trigger Mechanism

The Trigger Mechanism behind most recent Muskets is quite simple now but would be confusing for the older guns, a spring pulls back on the striker but the trigger must be pulled to realize the lock the spring pull's the striker forward making the flint spark, this also scratches and chips the flint, there are a few types of flint, from really good to really bad. flint is also very common in Henvire.

Shape Counts!
the shape of the flint has quite the effect, poorly shaped flint can cause Poor accuracy, twin shooting (when the gun fire's again without pulling the trigger), jamming, and it can even completely ruin the gun, the best shape is a 3cm oval you can use a 4cm oval but it may jam the gun.

Charcoal Coating
coating a piece of flint in charcoal is quite an improvement, It helps because the sparks from the flint ignite the charcoal making a tiny explosion giving it a extra kick when exiting the barrel, the charcoal coating will go before the flint, Carbon monoxide level's increase from the guns firing, you need Charcoal Coating to shoot bullet's unlike musket ball's that can be fired whenever

Pretty Useless powder
After a piece of flint is completely used up it turns white, sometimes it completely breaks apart and becomes a powder, this white powder is completely useless even as a dust cloud for cover, if it doesn't come out easily you should see a gun smith so you don't break it, if your gun starts shooting white smoke it's ruined and your going to need a new musket, other times the flint will just turn white nothing about it changes and you should still just get a new piece of flint.

More flint uses
at first when the handy canon was made each piece of flint could only be used once after firing the flint would shatter into bits and escape with the musket ball, now you have more then 100 shots before the flint needs to be replaced,
