This is a most excellent place for technology news and articles.
russia and nk uses 152mm, not 155mm
I am aware. The 3 mm calibre difference has no impact on fabrication costs.
the difference is in different cost of workforce, different manufacturing standards, different materials, different fill, different fuze (easily 1/3 of cost),
In terms of bucks per kill the West is doing an order of magnitude worse.
