About 15 years ago, I resumed my mostly pistol shooting when I began to shoot a defensive "game" called IDPA. At that time most of my shooting buddies reloaded, so as to precisely tailor their pistol loads to their guns and the necessary "power-factor", a load that minimized recoil, and yet met IDPA for power. I started with a progressive press for pistol ammo, and then began to load precise ammo for my rifles with a single stage. The rifle because ammo for my vintage rifles was just expensive or hard to find.
I have't bought any ammo for at least a decade other than .22. So I suggest a "long-game" for folks who want to continue to shoot when the periodic shortages and expensive ammo re-cur. Right now reloading equipment and components are scarce, but with time and patience, one can slowly gather up what is necessary.
Besides, making one's own ammo is a contemplative, relaxing and rewarding hobby. In past years, I always bought components when I came across them so I can probably continue to shoot for the rest of my life.
While by now my equipment is extensive to make my rifle and pistol ammo, it isn't necessary to begin with much more than a sturdy work table and a single stage press, a die set for your pistol, a scale, caliper and when you acquire bullets, cases and primers, begin the very rewarding hobby of "rolling your own."
Ask friends to see how they reload, read the forums, and begin your search. Right now primers are scarce, but be ready when they become affordable again. Bullets and cases are available.
As for dies, when I recently bought my first modern revolver, a 38/357 N frame, it only took me a month to have two sets of dies for that caliber, and by then I had cases and bullets. Enough "stuff" that I made and mailed 100 38 special rounds to somewhen who bought a S&W but had nothing to shoot.
So.....accept what the present and future are going to be for recreational shooting, and begin your Plan B. A single stage press with dies and other equipment will run you less than maybe $400. Before too long, you will be shooting again.
All the best, and stay safe, SF VET
