Brass is the only real bottleneck I face when it comes to ammo. That said, if on RanGen, its not too big an issue but it does reach a point that I have to travel further as I strip a town/city of every available brass resource. Traders fortunately do help abit but its also subject to luck on whether they stock it as well.
I'm more in favour of there being like a copper resource node to mine. Though it would mean Zinc would have to be available in some form as well. I do remember proposing in another thread quite some time back to include copper ore veins to mine (we can expand electrical items and such to require copper ore instead of iron to craft too). Zinc ore would drop as a by product from mining all other resources like iron, coal, lead, potassium and copper even.
