ezra650 nailed it. The US has increased supply of 155mm artillery shells as it turns out the military itself owns the production facility. That powder has to come from somewhere. And one major supplier was in the Donbass region, now recently under Russian control. As a side note, the equipment at this facility looks older than the workers, and that is saying something!
in Finland, home of VV, they just further escalated just yesterday.
I don’t see prices going anywhere but up as the raw materials are in ever increasing demand
