Thanks guys,
Henry: Scrounging for silver is fine. But the cadre is in a modest sized city with access to resources and labor. They asked about costs and I'm trying to work the out in a non-ad hoc way. If they were stuck in some tiny hamlet in the middle of nowhere, scrounging would be their only option. But since you raise the point, I'd better make some decisions about how many shots can be made from a pound of silver, because that will come up eventually.
Herid: yeah, but 300 RP for 12 shots just seems ridiculously expensive. Then again, if that's the price I were to quote them, you can bet they'd scrounge. I'd let them use Marksman to make a bullet-no need for esoteric knowledge. You just need a really hot fire (hotter than a campfire) and a mold. Not much else to it.
Right now, I'm leaning towards either x5 or x10 cost for silver bullets, more for silver arrows. Maybe not as realistic...but maybe I need to get over that and send the out to raid silverware caches.
