Sometimes metallic handloading is just plain tedious. I can't say I hate it, but at times it's sure not intellectually rewarding. Mindless.
I do detest loading shotshells, though. Did it, hate it, and quit. To me, a shotshell only needs to go "bang" and spray a cloud of shot. A shotgun is little more than a hunk of conduit screwed to a 2x4.

Real shotgunners can call me a heretic, but I stopped using my MEC years ago. It gathered dust and I eventually sold it. Instead I just buy cheap shotshells. Not that I'm much of a shotgunner, but the urge to break things visits now and then. Fortunately, it subsides when the weather turns sucky.
