They Build a Better Bullet

Objectives
Obtain 200 Dark Iron Bullets.
 * Dark Iron Bullet x200

Description
Those gorge-digging dwarves do at least one thing right: they make very high-quality bullets. I've been unable to reproduce their results, so I've taken to stealing whatever bullets of theirs that I can find.

Ye want my help? Get me a couple hundred bullets from those below.

I'm sure they'll be happy to give ye their bullets one at a time, but you might find it faster just to look for the crates filled with them.

Progress
A real woulda caught the bullets with  teeth.

Completion
I'll just divvy these up amongst the guards. Ye have my thanks.
