when my figher/ranger run out of musketballs during a fight, it seems to decrease the charges of their blunderbusses - that way, i end up having one of these babies without zero charges, which means they are of no use at all - is there any way to re-charge them? so far, i have been selling them and bought a new bb when i came around to the umpani base camp.

just select some musket balls with the mouse so that they become the mouse pointer and then click on the blunderbuss and it will "recharge"
