If you are starting from scratch, and don't have alot of money, don't worry. I started reloading with a lee loader kit, and loaded my first several hundred rounds of mosin nagant ammo with it. I paid about 24 dollars for it from sirmailorder. To measure powder, there's a scoop, you simply have to choose one of the types of powder indicated in the instructions, with an appropriate bullet weight. Most of the options given are very common combinations. Everything else you need, except a hammer is included.
There is alot of very fancy, very flash equipment, and the job of the advertisements is to convince you that you simply cannot possibly reload without gadgets A, B, and C, and possibly D, and that brand "X" is all there is that is worth buying, and you might die if you buy brand "Y"
The fact is, though, that men on horseback were reloading their cartridges,
safely and accurately, since the beginning of the cartridge, usually with some pretty crude hand tools.
Remington loaders circa 1875
Savage all-in-one 1904
As time has gone by, I've upgraded my equipment, and have all the nice carbide dies, and chamfering tool, case neck expander, auto primer, neck sizer dies, trimmers, bullet lubrisizer that automatically applies gas checks to cast bullets, shotshell roll crimper, precision scale....etc..etc..etc..
It's nice to have gadgets, I'm a gadget kind of guy, but that $24 lee loader did everything I needed it to do, did it well, and I still have it.
