Bullet schematics question

[Eldomm]

Hi everybody,
I have a (maybe) stupid question: I bought the "Bullet" schematics, but I cannot use it because some requisite is missing. I wonder what is/are the requisite/s to use this? Maybe to have other schematics in Explosives?
Anyone can help?
Thanks in advance,
Eldomm

You need to have enough skill in the appropriate areas. I seem to remember that when you look at schematics there are little symbols, which correspond to different skill trees and a number next to them. The number is the amount of skill you need in that area to build that item.

If memory serves me correctly you'll need one point into the explosives and chemistry trees to make bullets.

Thanks!
yesterday though I figured it out. It was enough to have one point in explosives.

i never quite understood that schematic thing so i boosted my explosives and gun smithy skills to the highest rank in order to make bullets, but then i figured out that those numbers had a meaning
