Ammo companies are working 24/7 to meet current demand.
FYI - BO (you remember el Presidente)?
He passed a Presidential Decree about 3 - 4 weeks ago that prevented the Military from reselling their brass which is a very important source for ammo manufacturers.
The expensive part of manufacturing ammo is the making of the brass (which can be used over and over and over again).
The Military now has to shred any spent cartridges and resell the brass that way which drops the value of the brass to 1/20 the original value.
