Base price of 30 ... *2 for being worked into gunpowder, then there is no bonus for double working something.
It does more than add clicks,it adds trips to the mine and back which adds more time.
Is it at all possible to seperate cost and time?
Im not 100% on the price of 50 rounds right now but I believe its something like 450 caps and I would have absolutely no problem with getting that same ammount for 100 if it means I have more time away from mines and benches.
If you want to make enemies, try to change something.
