We’ve had a hard time getting ammo too. But there aren’t a lot of ammo companies that are publicly traded.
If our society really, really goes into the tank, people should consider a back up weapon if the modern ammo one needs is gone. I have a reproduction Remington 1858 revolver and a repro Zuave with reproduction Minie bullets and plenty of black powder and Pyrodex. I do need to get some caps.
