Should you start reloading?
Once you get started, after while you won't be loading just 9mm, .223 and 20gauge. Once you have the equipment, you'll figure that "I already have most of the stuff, all I need to buy are the dies for .44-40 and I'll get that neat lever action." This will then happen many more times until your are loading 10or 15 metallic calibers; it may not proliferate quite so fast with shotgun.
After that, you'll discover how cheap and versatile cast bullets are and you'll get into that.
Pretty soon, you'll be loading 28 gauge rifled slugs, 8x50R Austrian, and .41 Long Colt.
