The item description says
“Reinforced Bullet Mold: Craft up to 4 bullets using 1 use of the Craft Basic Engineering Schematic skill and the Bullet schematic, at the normal cost per bullet”
Where this version of the bullet mold is not consumed with use, if someone owns a single reinforced bullet mold, and has the materials to produce 8 or 12 bullets, and has 2 or 3 uses of craft Basic Schematic, can a person use the reinforced bullet mold multiple times per BGS, or is it single use per BGS?
