Disagree. Shotshell is all I really reload, although I'm currently trying to learn how to use the classic lee loaders for 45acp and 30-30 win black powder. I find shotshell stupid easy, but I just do black powder loads. Stuff the case with black, put whatever cotton I've got kicking around as a wad, dump the same volume shot, then candle wax to seal. Easy peasy. In comparison to pistol and rifle calibers you have to trim cases, open up the end to stuff the bullet into, and other more complicated crap.
I'm selling two new classic lee loaders in 223 and 308 in the EE right now cuz I decided I'm never going to bother reloading them. I don't have the space for all the primers and brass and projectiles I'll need.
