It’s not difficult to start, but it requires intense attention to detail to do well (and safely). For instance - I usually a single-stage press instead of one of the fancier turret presses I have, because I like to weigh every ten rounds that come off to ensure consistency. Likewise, I spend the time necessary to choose a powder that fills more than 50% of the case volume so a double charge will overflow and be obvious. That’s even before I start load development, which is often specific to a single firearm, bullet, and even primer sometimes.

Speaking of primers... there are none out there for sale, and there haven’t been since very early 2020. Reloading equipment is easy to find, supplies not so much.
