More reason to learn to load your own ammo.
Been doing that a while now. Now components are getting pricey and hard to find.
Brass has a finite lifetime. Careful inspection for a cracked case mouth and dimensions (trim as necessary) is important. Annealing work hardened brass might get a little extra life, but most people don't go that far. You still have to replace the primer, power and bullet each time. Rising prices for metal are making the components more expensive. Rising fuel prices are also impacting the delivery cost of those components. Reloading is still an economic "win" over buying factory ammo in many cases. I reload all my big bore revolver ammo. I've recently started reloading my .30 caliber cartridges as it allows me to make "puffball" rounds with 100 gr Plinker bullets for 100 yard target shooting.
