Back in the day, I could go down to the local gun shop and get the components I needed in 5 minutes and it was cheap, That all changed when Clinton imposed the original Assault Rifel (AK ban and pre-ban) legislation which, incidentially was drafted in part by our favorite Senator, Diane Feinstein, which 'sunsetted' but the die was cast.
I've continuously anticipated future disruptions in supply chain economics and acted accordingly with components, maintaining my inventory at levels that associate with disruptions that I knew would occur again.
Unlike the old days when propellants came in cardboard cartons and the propellant had a definite shelf life, modern technology has made packaging an indefinite shelf life. Propellants come in vacuum sealed plastic bottles and jugs that last indefinitely. Projectiles are packaged in plastic boxes that you can stack in the corner, same with primers so there is little excuse not to carry stock. It's like my business. I don't carry just one of a part, I have multiples on hand, all the time and I order using an inventory level and useage factor. Same applies for reloading supplies, in fact, I just ordered a couple 8 pound kegs of powder. Sure, it's on back order but I have enough for the forseeable future.
We live in a 'I want it now' society. Problem is, it really don't work, especially in this case.
Patience is a virtue that comes with age and experience. I practice both.....
