You can buy loaded rounds for what it takes in time and labor to re-prime that stuff. Plus the decapping is maybe 60% successful once you get the hang of it.
You can also re-swage the fired rounds and insert the cores in new gilding metal if you want to go that far, there is tooling to make new jackets from copper cups.
Some things are not practical and impossible from an economic standpoint.
That there are no commercial operations that mess with berdan primed brass should be a tell.
"All roads are now open in Barrett Township again. The suspect still has not be caught and PSP advised me they would be doing another press release shortly, if they haven’t already. I’d just like get it out to the community to remain alert and vigilant and notify 911 if they see anything suspicious. It would be GREATLY appreciated if you could also mention to the public that police are asking the community to please refrain from shooting guns outside until Eric Frein has been apprehended."
