I got into reloading many years ago for accuracy reasons, not for savings. When shortages come up like this its nice to have the supplies to load my own cheap 223. I buy a lot of pulled M855 bullets or even new pre-colored steel core bullets for very cheap. Only takes me a few hours to load 1000 rounds for the next days shoot.
If you have not started reloading its worth the $100 to get a simple Lee kit and start learning the basics.
