I got into reloading a few years back when I really just wanted another way to enjoy my firearms hobby. I studied around a lot, read a lot, and then went and had someone show me the ropes. I invested in a small single stage press, over time was either gifted or bought other components needed, and then got started slowly. Loading 50-100 rounds, heading to the range to see how they shot, then back to the garage. I didn't get into it to craft the most accurate loads or make boutique rounds or anything fancy. I just wanted to shoot more with the same amount of money. Because reloading does not save money, you just get to shoot more with the same amount. It is just like most things with firearms, or anything, complacency kills. Measure twice, check everything, never assume, and write everything down.
It should be taken seriously, because a mishap can be annoying at best, or absolutely catastrophic at worst...from having to hammer out a squib, to bulging a barrel, to a massive kaboom. But with that said, the reasons people get into reloading can vary from "I just want to shoot a lot." to "I want the most accurate rounds I can possibly produce for this one specific rifle/pistol" both are absolutely viable reasons, as well as all reasons in between, and it can overlap.
I don't reload much anymore because ammo got cheap for a while and my time was at a premium...and it still is. With this whole mess going on as well as four children my range time has dwindled to nearly nothing compared to what it has been in the past. But the good news is, brass and bullets don't expire, and the press is out there waiting. All I need to do is grab some fresh powder and primers and I am back to pulling the handle.
