Could make things worse?
Have to wait for the investigation but we would probably not hear anything further... :(
Hard to say from the article. No indication on how extensive plant damage was or even if there was any. In a metal foundry you can have a pretty significant accident in human terms without really affecting production capacity.
I am not sure where Starline sources their brass cups they draw into cartridges. I would imagine as big as they are they don't single source, but maybe. And, since Olin Brass is no longer aligned exclusively with the firearms industry I would likewise expect others to not be single sourcing raw materials.
