I currently reload my own cartridges for the following calibers:
.223/5.56mm .308/7.62mm .44 Magnum
.45 ACP .45 Colt .454 Casull
Basically . . . metalic cartridges fall into two types: Rifle (bottleneck) and Handgun (straight walled). I haven't bought any centerfire ammo in years because I reload my own at 1/4 to 1/2 the cost, and, handloads are usually as good or better than any premium ammo you can buy. I've taught reloading classes in the past and could teach you a basic reloading course. If you want to learn how to craft your own ammunition, contact me.
I have also recently got into casting my own lead bullets for the .44mag, .45 ACP, and .454 Casull. Below are some pictures related to reloading and casting:
